ABSTRACT:
A cross-linked polymer-supported 4-(N-benzyl-N-methylamino) pyridine material and process for its preparation in high yield and having effective physical and catalytic properties. The polymer-supported catalyst is characterized by the suspension copolymerization of an organic phase containing the corresponding vinyl-substituted pyridine monomer, a styrene monomer, and a suitable cross-linking agent and free radical-generating catalyst in the presence of an aqueous phase containing a cellulose ether derivative as the stabilizing agent. A purified acid salt of the vinyl-substituted pyridine monomer useful in polymerizations and stable for storage as either a solid or an aqueous solution.
