Process for preparing an alternating copolymer of a conjugated vinyl compound and an olefinic unsaturated compound

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 lea...

Zusammenfassung: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 halogenocompound 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.
