Title: Improvements in copolymers
IPC: C08F22/28
Filed: 1949-03-16
Abstract: Copolymers are produced by heating a di-2-propenyl itaconate and from 0.1 to 10 molar equivalents of a 2-propenyl chloride at a temperature in the range of 25-120 DEG  C., preferably 50-110 DEG  C., and for a time sufficient to effect an adequate degree of reaction, usually 1 to 70 hours.  The course of the copolymerization may be followed by noting the increase in viscosity of the reaction mixture.  The heating may be conducted in the presence of an organic peroxide catalyst such as acetyl peroxide, benzoyl peroxide and tertiary butyl hydroperoxide in the proportion of 0.1 to 20 per cent by weight of the reactant mixture.  The di-2-propenyl itaconates are esters of itaconic acid with alcohols having the formula R.CH=CR1-CH2OH and the 2-propenyl chlorides have the structural formula R.CH=CR1-CH2Cl, where R is hydrogen, chloromethyl, lower alkyl or phenyl, and R1 is hydrogen, chlorine, chloromethyl, hydroxymethyl or lower alkyl, preferred esters being the allyl and methallyl esters and preferred chlorides being allyl chloride, methallyl chloride, 2,3-dichloropropene, and 3-chloro-2-chloromethyl propene.  The products may be purified by repeated solution in a solvent such as acetone and reprecipitation with a non-solvent such as n-hexane and may be moulded to form rods, blocks or sheets or dissolved in organic solvents and used as coating, laminating and impregnating compositions.  The copolymers by the application of heat and/or a catalyst can be converted to an insoluble infusible state by further polymerization or by copolymerization with other polymerizable organic compounds such as butyl methacrylate, vinyl butyrate, styrene, allyl acrylate and diallyl fumarate, and dyes, pigments, fillers and plasticizers may be incorporated with the copolymers at the soluble fusible stage prior to the final cure.
