Abstract
PURPOSE: To prepare efficiently a monoolefin-α,β-unsaturated dicarboxylic acid anhydride copolymer useful as a dispersant for dyes or pigments, etc. suppressing the formation of deposits on the wall of the polymerization vessel, by adding an ethylene-vinyl ester copolymer to the polymerization system as a dispersant.
CONSTITUTION: A mixture comprising (A) a monoolefin (e.g. isobutylene, etc.), (B) an α,β-unsaturated dicarboxylic acid anhydride (e.g. maleic anhydride, etc.) and (C) an ethylene-vinyl ester copolymer (e.g. ethylene-vinyl acetate copolymer, etc.) as a dispersant, is radically polymerized to give a copolymer. Preferably the component (C) contains 5W50 wt.% of the vinyl ester and has a melt index of 5W 1,000 g/10 min.
