Abstract
The high mol.wt. polymers are obtained as solns. contg. 30-40% solids by (a) emulsion polymerisation with 2-20% polymerisable solids (b) simultaneous addn. of co-polymerisable surfactants such as vinyl cpds. with various degrees of ethoxylation, of formula (I), in which R is H or 1-10C linear alkyl, and n is 2-50, in 0.1-3% concn., and (c) adjusting the polymer content to 30-40% by azeotropic distn. of excess solvent.
