Under the Seventh Amendment a polymer is defined as a substance which: Consists of molecules which include a sequence of one or more types of monomer units (the reacted form of a monomer in the structure); Show a molecular weight distribution primarily due to differences in the number of monomer units in the individual molecules; Contain 50% or more by weight of molecules containing a sequence of at least three monomer units covalently bound to at least 1 other monomer unit or reactant; Contain less than 50% by weight of molecules with the same molecular weight A polymer becomes notifiable when it contains 2% or more of a new substance as part of its structure Guidance on Polymer Notification

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
