Notes:
The quaternization of poly(ar-vinylbenzyl chloride) with trimethylamine is shown to be a nucleophilic displacement reaction, the kinetics of which are complicated by several factors, notably differences in the reactivities of o- and p-chloromethyl groups (position isomerism), differences in the reactivities of groups as a function of the reacted or unreacted status of immediately adjacent groups (neighboring group effect), and differences in the reactivities of groups arising from the microtacticity of the polymer segment (configurational effects). Estimates of mean rate constants, activation energies, and preexponential factors are given for high purity poly-p-vinylbenzyl chloride and for the analogous ortho polymer.
