ABSTRACT:
A nonaqueous resin dispersion in which particles of a low molecular weight polyolefin are finely and uniformly dispersed, which dispersion is obtained by the polymerization of a vinyl monomer (C) in the presence of 20 to 90% by weight of a substantially saturated polymer (A), based upon the total weight of the reactants (A), (B) and (C), and a low molecular weight polyolefin (B) dispersed finely therein. The resin dispersions of the present invention contain the low molecular weight polyolefin finely and uniformly dispersed such that it has an average particle diameter of not more than 10.mu. and preferably not more than 1.mu.. According to the Invention, the polyolefin is more finely and uniformly dispersed than previous dispersions produced by mechanical melt-dispersion of low molecular weight polyolefin and a resin.
