ABSTRACT:
A stable polymer dispersion in polyoxyalkylenepolyamine is provided by the in situ polymerization of at two different monomers selected respectively from (a) a first monomer capable of forming a homopolymer which does not precipitate out upon the in situ polymerization and (b) a second monomer capable of forming a homopolymer which precipitates out upon the in situ polymerization. The dispersion is useful as a raw materials of polyurea RIM, forms, elastomers and other products.
