ABSTRACT:
This invention relates to polymer dispersions prepared by the in situ polymerization of an ethylenically unsaturated monomer or mixture of monomers in a chain extender in the presence of a free radical polymerization initiator and a polyamide stabilizer. The invention also relates to mixtures of the polymer dispersions with compounds having two or more active hydrogen atoms as determined by the Zerewittinoff method. These mixtures are used to prepare polyurethane products.
