Abstract: Copolymers e.g. alternating, of a compound of the formula (1) <FORM:1123722/C3/1> wherein R1 and R2 are hydrogen or a halogen atom, a hydrocarbon or halogen-containing hydrocarbon residue having 1 to 20 carbon atoms; and (2) a vinyl compound selected from acrylonitrile and a compound of the formula <FORM:1123722/C3/2> wherein Z is oxygen or a sulphur atom, Y is a member selected from Z1R, Z1H, Z1Me, NR1R11, <FORM:1123722/C3/3> and R radicals, a halogen or hydrogen atom, Z1 is an oxygen or sulphur atom, R is a hydrocarbon residue, R1 and R11 are the same or different and selected from hydrogen and a Cl-20 hydrocarbon residue, RVI is a divalent hydrocarbon radical having 1 to 20 carbon atoms, Me is a monovalent metal or ammonium group and Me1 is a divalent metal in the presence of an organoaluminium halogen compound of the general formula AlR1nX3- n, wherein R1 is a hydrocarbon residue, X is a halogen atom and n is 1, 1 1/2 or 2, and/or a mixture of at least two components selected from at least two of the following groups: (a) AlR1nX3- n; (b) AlR113, wherein R11 is a hydrocarbon residue; and/or (c) AlX13, where X1 is a halogen atom, and oxygen or an organic peroxide.  The Specification contains extensive lists of suitable monomers, organo-aluminium compounds and peroxides. The polymerization is preferably carried out at very low temperatures.  In Example 1, methyl acrylate was copolymerized with styrene in the presence of toluene, ethylaluminium sesquichloride and benzoyl peroxide, in Example 2, the same monomers as Example 1, but various peroxides replaced benzoyl peroxide, in Example 3, as 1, but lauroyl peroxide was used instead of benzoyl peroxide, in Example 4 methyl acrylate and styrene were copolymerized in the presence of toluene, ethylsesquichloride and oxygen and under the same condition methyl acrylate was replaced by acryloyl chloride, acrylic acid, N-ethyl acrylamide, acrolein, methyl vinyl ketone, cyclohexyl acrylate, and sodium acrylate, and styrene was replaced by propylene, ethylene, alpha-methyl styrene, allylbenzene, octadecene-1, and vinyl cyclohexane, in Example 5, methyl acrylate was copolymerized with propylene in the presence of toluene, ethylaluminium sesquihalide, and benzoyl peroxide, Example 6 was as Example 5, except n-butyl acrylate replaced methyl acrylate, Example 7 was as Example 5 except propylene was replaced by liquid isobutylene, in Example 8, methyl methacrylate and liquid propylene are copolymerized in the presence of aluminium bromide, triethylaluminium, and oxygen, in Example 9, under the same conditions methyl methacrylate was replaced by acrylonitrile, in Example 10, methyl acrylate and vinyl chloride were copolymerized at -78 DEG  C. in the presence of methylene chloride, cumene hydroperoxide, and ethylaluminium dichloride, the vinyl chloride can be replaced by vinylidene chloride, allyl chloride, and 2-chloro-propene-1, and in Example 11, under the same conditions as Example 1, but with the addition of cumene hydroperoxide an alternating copolymer of methyl acrylate and styrene was obtained.
