Abstract
Described are unique polymerization processes for preparing linear polyvinylpyridine polymers as well as unique linear polyvinylpyridine polymer compositions. The processes involve the use of an alkylpyridine anion as an anionic polymerization catalyst and result in linear polyvinylpyridines having alkylpyridine end groups homologous to the pendant pyridines of the polymer. Processes of the invention are particularly advantageous in preparing relatively low molecular weight linear polyvinylpyridines without the need to use large amounts of catalyst to achieve the same.
