Polymer Definitions

The difficulties of devising a basis for conveniently classifying various polymerizations in an appropriate manner have been discussed earlier in this chapter and several borderline examples which offer particular difficulty have been mentioned. One of these, the polymerization of the N-carboxyanhydrides, falls within the definition of a condensation polymerization, proceeds by a mechanism resembling a vinyl addition polymerization, and yields a product which possesses the structure of a typical condensation polymer. Definitions have been... [Pg.61]

This chapter discusses the regulatory effect for a substance meeting the polymer definition in these jurisdictions, and a discussion of several special topics the two-percent rule, post-reactions and devolvement of pre-polymers, and nomenclature issues involving epoxy polymers derived from hisphenol-A and epichlorohydrin. We shall also discuss the curious requirement under REACH that monomers and other reactants in reacted form must he registered even though the polymers manufactured from them do not, including consideration of confidential information which may he compromised through this provision.
