Abstract
PURPOSE: A water-repelling copolymer excellent in solubility and surface activity in water, prepared by saponifying a copolymer comprising a vinyl ester or an α- olefin, a specific sulfonate monomer and vinyl acetate.
CONSTITUTION: A copolymer prepared by saponifying a copolymer having the following three components: (A) at least one monomer selected from the group consisting of a C8 or higher fatty acid vinyl ester, a C8 or higher alkyl vinyl ether and a C8 or higher α-olefin, (B) a monomer represented by the formula, wherein R1 is H or a lower alkyl; R2 is an alkyl; R3, R4 and R5 are each H or an alkyl and M is H or a cation (1 eq.) and (C) a vinyl acetate. The fatty acid vinyl ester, if it is of C7 or lower, has no effect because such an ester does not have satisfactory hydrophobic effects and is susceptible to hydrolysis of the ester linkages during alkali saponification.
