Abstract

Graft polymers are prepared by reacting a polymer containing fluorine, chlorine or bromine in the presence of a Friedel-Crafts catalyst with an aromatic hydrocarbon which is capable of being alkylated by means of, or an olefinic compound which is capable of being polymerized by, a Friedel-Crafts catalyst, e.g. aluminium chloride, titanium tetrachloride, tin tetrachloride, ferric chloride and boron trichloride. Halogen containing polymers specified are polyvinyl chloride, copolymers of vinyl and vinylidene chlorides, polyvinyl fluoride, polyalphachlorostyrene, polytrifluorochloroethylene, chlorinated polyethylene and rubber hydrochloride. Aromatic hydrocarbons and olefinic compounds specified are benzene, alkyl benzenes, e.g. toluene, naphthalenes, styrene, alpha - methylstyrene, p - alpha - dimethylstyrene, methoxystyrenes, p-dimethylaminostyrene, nitrostyrenes, fluoro-, chloro-, and bromo-styrenes, indole, coumarone, indene, isobutene, 2-methylpentene-1, butadiene, isoprene, cyclopentadiene, vinyl ethers, oxacyclobutane, dihydrofurans, anethole, silbene, 4,41-dimethoxystilbene, 1,11-diphenylethylene. The reaction is carried out in an inert solvent such as aliphatic or aromatic hydrocarbons and aromatic nitro and halogen substituted compounds which are not easily susceptible to the Friedel-Crafts reaction, e.g. nitrobenzene and chlorobenzene.
