A Kinetic Study of the Quaternization of Tertiary Amine Functional Groups in the Poly(VinylpyridineThe aim of this paper was to study the reactivity of a functional group in a small molecule in comparison to that group bound to a macromolecular backbone. The main parameters which determine the value of the reaction velocity constant of such a functional group are:

Modification of Polymers Containing Lewis Base Functional Groups via Condensation with Lewis Acids,Polymer modification can be effected via many routes. Our work currently involves the condensation of polymers containing Lewis Bases (nucleophiles) with mono and dihalo acid chlorides containing metals (1–14) as illustrated below.
