ABSTRACT:
Suspension polymerization a vinyl monomer in the presence of from about 0.01 to 2.0%, by weight of the total monomer content, of a carboxymethyl hydrophobically modified water-soluble, nonionic cellulose either polymer alone or in combination with an inert electrolyte or inert polyelectrolyte is disclosed. The presence of the carboxymethyl hydrophobically modified water-soluble, nonionic cellulose ether polymer alone or in combination with an inert electrolyte or inert polyelectrolyte provides suspension polymer beads of narrower polydispersity and clarity, and results in minimal latex polymer (emulsion polymer) by-products.
