ABSTRACT:
Macromonomers are obtained by successively reacting an oligomer or polymer containing at least one hydroxyl group with a cyclic carboxylic anhydride in an amount of at least one mole of the anhydride per hydroxyl group, and reacting the product with a compound containing a single epoxide group and a single polymerizable double bond, in such proportions as to esterify all carboxyl groups in that product. Graft copolymers which are useful as steric stabilizers for dispersions of polymer particles can be made by copolymerizing the macromonomers with other polymerizable monomers.
