Definition von polymerization im Englisch Englisch wörterbuch: The chemical process, normally with the aid of a catalyst, to form a polymer by bonding together multiple identical units (monomers); A chemical reaction in which one or more small molecules combine to form larger molecules A hazardous polymerization is such a reaction that takes place at a rate that releases large amounts of energy If hazardous polymerization can occur with a given material, the MSDS usually will list conditions that could start the reaction and–since the material usually contains a polymerization inhibitor–the length of time during which the inhibitor will be effective; A chemical reaction in which small molecules (monomers) combine to form much larger molecules (polymers) A hazardous polymerization is a reaction that occurs at a fast rate, and releases large amounts of energy Many monomers are hazardous in the liquid and vapor states, but form much less hazardous polymers An example is vinyl chloride monomer, which causes cancer but forms the relatively non-toxic polyvinyl chloride (PVC) plastic; in petroleum refining, polymerization refers to the combination of light, gaseous hydrocarbons, usually olefins, into high-molecular-weight hydrocarbons that are used in manufacturing motor gasoline and aviation fuel The product formed by combining two identical olefin molecules is called a dimer, and by three such molecules, a trimer See polymer; Reaction of two molecules to form a polymer; the length of the polymer chain is specified by the number of repeat units in the chain (degree of polymerization); a process in which many small molecules (monomers) are joined together to form a large molecule; The act or process of changing to a polymeric form; the condition resulting from such change; Any process in which monomers combine chemically to produce a polymer. The monomer molecules which in the polymer usually number from at least 100 to many thousands may or may not all be the same. In nature, enzymes carry out polymerization under ordinary conditions to form proteins, nucleic acids, and carbohydrate polymers; in industry, the reaction is usually done with a catalyst, often under high pressure or heat. In addition polymerization, monomers are added successively to the reactive ends of a growing polymer molecule, similar to adding links to a chain; during the reactions, no by-products are formed. In condensation polymerization, growth of the polymer advances stepwise monomers having reactive functional groups combine into larger molecules with their own functional groups; each reaction splits off a small molecule, often water, as a by-product; {i} combination of two or more separate molecules to form a more complex molecule (also polymerisation); A chemical reaction in which two or more small molecules combine to form large molecules containing repeated structural units; A chemical reaction in which two or more small molecules combine to form larger molecules that contain repeating structural units of the original molecules A hazardous polymerization is the above reaction with an uncontrolled release of energy; A chemical reaction in whch one or more small molecules combine to form larger molecules A hazardous polymerization is such a reaction that takes place at a rate that releases large amounts of energy; Process of forming a polymer by combining large numbers of chemical units or monomers into long chains; The chemical combination of similar-type molecules to form larger molecules; A chemical reaction in which one or more small molecules combine to form larger molecules A hazardous polymerization is a reaction that takes place at a rate that releases large amounts of energy If hazardous polymerization can occur with a given material, the MSDS usually will list conditions that could start the reaction and--since the material usually contains a polymerization inhibitor--the length of time during which the inhibitor will be effective; The act of joining simple molecules(monomers)into giant ones (polymers) to form plastics, fibers, elastomers and non-structural resins; A chemical reaction in which the molecules of a monomer are linked together to form polymers; The reaction occurring when two or more molecules of a compound are united to form a more complex compound with a larger molecular weight; Chemical reaction in which one or more small molecules combine to form larger molecules A hazardous polymerization is such a reaction that takes place at a rate that releases large amounts of energy that can cause fires or explosions or burst containers Materials that can polymerize usually contain inhibitors that can delay the reaction; A chemical that can react with itself to form long chain molecules; Chemical reaction that links monomers to form polymers; A chemical reaction in which the molecules of monomers are linked together to form polymers via two principal reaction mechanisms Addition polymerizations proceed by chain growth and most condensation polymerizations through step growth; An undesirable change in the composition of a food fat involving intermolecular agglomeration or clumping of the normal chemical units of fat and its decomposition products into larger and insoluble chemical units; a chemical process that combines several monomers to form a polymer or polymeric compound; The process of combining two or more molecules to form a single large molecule; The formation of a polymer from monomers by chemical reaction There are several types of polymerization processes; A chemical reaction usually carried out with a catalyst, heat, or light, and often under high pressure, in which a large number of simple molecules combine to form a much larger chain-like macromolecule; the chemical reaction in which high molecular mass molecules are formed from monomers; The combination of many small molecules to form large molecules; Chain Polymerization

polymer: A polymer is a chemical compound with large molecules made of many smaller molecules of the same kind. Some polymers exist naturally and others are produced in laboratories and factories. a chemical compound that has a simple structure of large molecules (polymeres , from meros ). Any of a class of natural or synthetic substances composed of macromolecules that are multiples of monomers. The monomers need not all be the same or have the same structure. Polymers may consist of long chains of unbranched or branched monomers or may be cross-linked networks of monomers in two or three dimensions. Their backbones may be flexible or rigid. Some natural inorganic materials (e.g., the minerals diamond, graphite, and feldspar) and certain man-made inorganic materials (e.g., glass) have polymer-like structures. Many important natural materials are organic polymers, including cellulose (from sugar monomers; see polysaccharide), lignin, rubber, proteins (from amino acids), and nucleic acids (from nucleotides). Synthetic organic polymers include many plastics, including polyethylene, the nylons, polyurethanes, polyesters, vinyls (e.g., PVC), and synthetic rubbers. The silicone polymers, with an inorganic backbone of silicon and oxygen atoms and organic side groups, are among the most important mixed organic-inorganic compounds
