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.
In preparing a vinyl-substituted 4-(N-benzyl-N-methylamino)pyridine monomer for use in a polymerization, the improvement comprising the steps of isolating and purifying the crude monomer once formed with an acid sufficiently strong to form a salt with said monomer for stable storage pending later use.
As a monomer composition for subsequent use in polymerization, an isolated acid salt form of the reaction product from preparation of vinyl-substituted 4-(N-benzyl-N-methylamino)pyridine.
