Abstract
A process for manufacture of polymers comprising suspension polymerization of at least one vinyl monomer in the presence of from about 0.01% to about 0.4% by weight, based on the total monomer content, of at least one hydrophobically modified water-soluble, nonionic cellulose ether polymer and an inert electrolyte, and polymers prepared by same.
