Process for producing a non-aqueous system dispersed solution of polymers from polymeric peroxides

摘要

A non-aqueous liquid dispersion of polymers is obtained by a first step of copolymerizing one or more vinyl-type monomers with one or more polymerized peroxides, capable of further polymerization followed by a second step of copolymerizing the resulting copolymer having peroxy bonds therein with one or more vinyl-type monomers different than the one or ones used in the first copolymerization step, in an organic liquid which dissolves the polymers of the vinyl-type monomers of the first copolymerization but does not dissolve the polymers of the vinyl-type monomers used in the second copolymerization. The dispersion is splendid in dispersion stability and it is very useful as a thermosetting, film-type, coating composition.
