PROCESS FOR PREPARING PARTICLES OF OLEFIN-MALEIC ANHYDRIDE COPOLYMER |
摘要 |
A copolymer of an olefin and maleic anhydride is produced in the form of particles by co-polymerizing an olefin having 2 to 8 carbon atoms with maleic anhydride in a solvent capable of dissolving both co-monomers, but incapable of dissolving the copolymer in the presence of a dispersant of an oil-soluble, cationic copolymer comprising (a) ethylenically unsaturated monomer units having cationic groups of a quaternary ammonium salt and (b) lipophilic, ethylenically unsaturated monomer units. It has a relatively uniform particle size distribution. |
