Abstract
An aqueous liquid dispersion of polymers can be obtained by two steps of reaction comprising the first step of copolymerizing polymeric peroxide with vinyl type monomers, whereby copolymers having peroxy bonds therein are obtained and the second step of subjecting said copolymers having peroxy bonds therein to block copolymerization with vinyl type monomers which are different in kind from the one employed in the first step of reaction, whereby said copolymers having peroxy bonds therein are cleaved at the peroxy bonds thereof, thereby obtaining block copolymers with high efficiency.
