The document defines the terms most commonly encountered in the field of polymer reactions and functional polymers. The scope has been limited to terms that are specific to polymer systems. The document is organized into three sections. The first defines the terms relating to reactions of polymers. Names of individual chemical reactions are omitted from the document, even in cases where the reactions are important in the field of polymer reactions. The second section defines the terms relating to polymer reactants and reactive polymeric materials. The third section defines the terms describing functional polymeric materials.
This document defines the terms most commonly encountered in the field of polymers containing ionizable or ionic groups and polymers containing ions. The scope of the document has been limited to organic polymers. Inorganic materials, such as certain phosphates, silicates, etc., which also may be considered ionic polymers, are excluded from the present document. The terms selected are those that are widely used in the field of polymers containing ionizable or ionic groups and polymers containing ions. Only those terms that could be defined without ambiguity are considered. The terms are listed in alphabetical order, and cross-references to definitions given in other documents are provided.
Copolyamides were prepared in which azodibenzoic acid or azodianiline were incorporated into Nylon 66. The azobenzene residues were irradiated to produce trans-cis isomerization and the dark cis-trans isomerization was followed spectroscopically. In dilute solution, isomerization rates of the polymers were very similar to those observed in low molecular weight analogs, suggesting that incorporation into the backbone of a high molecular weight chain polymer does not hinder the isomerization process. There was no evidence of the isomerization being slowed down at polymer concentrations corresponding to extensive chain entanglements. In the copolyamide containing azodibenzoic acid residues, the cis-trans isomerization did not follow first-order kinetics, but part of the azo groups isomerized much faster than the low molecular weight analog. This anomaly could be due to the oxidation of some of the azo groups to azoxy during the polycondensation and this interpretation is consistent with the kinetic data but does not fit the spectroscopic evidence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
