Abstract
1358184 Graft polymers HERCULES Inc 15 July 1971 33377/71 Heading C3G A graft polymer is obtained from a polyether polymer which contains at least 60% by weight of monomer units which are halo-substituted at polyether chain carbon atoms and are halosubstituted hydrocarbon, halo-substituted hydrocarbon-oxy or halo-substituted hydrocarbon-oxyhydrocarbon radicals, the polyether polymer additionally having at least one hydrogen atom by replacing at least one hydrogen bonded to a chain carbon by a graft comprising monomer units derived from at least one free radically polymerizable ethylenically unsaturated monomer, and the graft polymer having a reduced specific viscosity of at least 0À2. The reaction of the polyether polymer with the grafting monomer may be carried out in the presence of a free radical catalyst, e.g. benzoyl peroxide. Numerous polyethers and grafting monomers are specified in the description. In the examples a copolymer of epichlorohydrin and ethylene oxide is grafted with (a) a mixture of acrylonitrile and styrene (1-8), (b) acrylonitrile (9-11), (c) styrene (12-14), (d) vinyl chloride (15), (e) maleic anhydride (17-19), (f) vinyl acetate (21 and 22), (g) methyl methaacrylate (23-26) and (h) vinylidene chloride (27); poly-(2-chloroethyl glycidyl ether) is grafted with vinyl chloride (16); and polyepiehlorohydrin is grafted with maleic anhydride (20).
