ABSTRACT:
An alternating copolymer of an olefinic unsaturated compound and a conjugated vinyl compound is produced by contacting said monomers with at least one organoboron halide or/and a mixture of at least one organo-compound of metal from Groups IIb, IIIb and IVb of the Mendeleev Periodic Table and at least one halogeno-compound of metal from Groups IIIb and IVb of the Mendeleev Periodic Table. A typical catalyst is ethylboron dichloride or a combination of triethylaluminum and tin tetrachloride.
