Abstract:
1. A process for the preparation of polymer dispersions, said process comprising reacting an alkylene oxide and a glycidyl ether in an emulsion polymerization reaction to produce a block copolymer of formula (1) in which R R R A is an alkylene unit having 2 to 6 carbon atoms, x is a number from 0 to 10, y is a number from 0 to 10, n is a number from 0 to 100, k is a number from 1 to 100, R m is a number from 1 to 500, with the proviso that (y+n) must be at least 1, and wherein said polymerization reaction is carried out in the presence of an olefinically unsaturated monomer in an aqueous phase.
