Abstract

PURPOSE:To make it possible to obtain a polymer having an excellent dispersion stabilizing effect for dispersed particles and excellent properties, by suspension- polymerizing an ethylenically unsaturated monomer in an aqueous medium in the presence of a modified PVA containing a cationic group in the molecule. CONSTITUTION:A polymer having excellent properties is obtained by suspension-polymerizing an ethyenically unsaturated monomer, e.g., vinyl chloride monomer, in an aqueous medium in the presence of a modified PVA containing, in the molecule, a cationic group, e.g., group of formula I, II, III or IV, wherein R<1> and R<2> are each H or a lower alkyl, B is a group of formula V or IV, R<3>, R<4> and R<5> are each H or a lower alkyl, X is an anion, A is a group connecting the N atom in B to the N atom in the amide group, R<6>, R<7> and R<8> are each H, a lower alkyl or a phenyl and R<9> is a lower alkyl. The polymer produced by this process has good plasticizer absorptivity, no fish eye and excellent properties. This polymer exhibits its high industrial value particularly in the polymerization of vinyl chloride.
