GRAFT PRESTABILIZING AND STABILIZING COPOLYMERS AND THEIR PREPARATION, PROCESS FOR OBTAINING DISPERSIONS OF POLYMERS/POLYOLS AND PROCESS FOR OBTAINING POLYURETHANE FOAMS
摘要
Prestabilizing copolymers comprising the product of the in situ reaction of a mixture of ethylenically unsatured monomers containing at least one mono-unsaturated monomer containing no groups which can be alkoxylated and one unsaturated monomer containing a group which can be alkoxylated, a prepolyol of low molecular weight and a polymerization catalyst as well as an alkoxylating agent for the abovementioned reaction product chosen from the group comprising ethylene oxide, propylene oxide and their mixtures, process for obtaining dispersions of polymers/polyols and process for obtaining polyurethane foams.
