Process for the production of paste-forming vinyl chloride polymers

摘要

A process for the production of paste-forming polymers of vinyl chloride by emulsion or microsuspension polymerization, utilizes as the auxiliary dispersant an alcohol glycol ether of the general formula <IMAGE> wherein R is an alkyl- or alkylene residue of 16-30 carbon atoms, R1 is H or an alkyl residue of 1-2 carbon atoms, and n is a number from 1 to 3. It is also possible to employ the predispersion method. The polymers yield pastes of low viscosity and an almost Newtonian fluid characteristic, and final products exhibiting a high resistance to fogging.
