Abstract
Copolymers of (1) an acrylic ester of the formula: <FORM:0967551/C3/1> wherein R1 represents hydrogen or a methyl group and R2 and R3 when not joined together represent C1-C2 alkyl groups and, when joined together, represent a saturated divalent aliphatic hydrocarbon group which with the carbon atom carrying R2 and R3 form a five- or six-sided carbocycle and (2) an acrylic ester different from (1) and of the formula: CH2=CHCOR, where X represents oxygen or sulphur, and R an alkyl, cycloalkyl, aralkyl, aryl, terphenyl, or alkoxyalkyl group, and present in an amount of between 0.5 and 25 mole per cent of the total polymer, are made by copolymerizing a monomeric mixture of the esters at a temperature between -20 DEG C. and -100 DEG C. in the presence of an organic solvent, and an organomagnesium compound of the formula, R11-Mg-Y wherein R11 represents an alkyl, cycloalkyl, aryl, alkoxyaryl, alkenyl, alkynyl, or aralkenyl group, and Y represents chlorine, bromine, or iodine, or is as R11. The copolymer is characterized by (a) crystalline properties including a melting point below which there is a temperature range within which the copolymer remains semi-rigid and flexible, and (b) freedom from tackiness at 20 DEG C. Ester (1) may be isopropyl, sec-butyl, tert.-butyl, 3-pentyl, 2-methyl-2 butyl, 3-methyl-3 pentyl, cyclopentyl, cyclohexyl, or 4-methyl-cyclohexyl acrylate. Ester (2) may be methyl, ethyl, n-propyl, n-butyl, 2-ethyl hexyl, n-octyl, dodecyl, or octadecyl acrylate, methoxyethyl, butoxyethyl, ethoxy-ethoxyethyl, ethylthioethyl, or octylthio-propyl acrylate, phenyl, tolyl, butylphenyl benzyl, methylbenzyl, phenylethyl, phenoxyethyl, trimethylcyclohexyl, dicyclopentyl, tetrahydrofurfuryl, or terphenyl acrylate. The Specification contains a long list of organomagnesium compounds. Exemplified compounds are phenyl magnesium bromide in diethyl ether, n-butyl magnesium bromide, diphenyl magnesium in diethyl ether. The copolymerization is usually effected in a hydrocarbon solvent such as toluene or xylene and the copolymer recovered by conventional techniques, e.g. by treatment with methanol, and aqueous hydrochloric acid. Specifications 884,733 and 967,552 are referred to.
