| Abstract: | Conditions for preparation of acetylene–butadiene random copolymers were investigated. Only a combination of organonickel compound and dialkylaluminum halide was able to copolymerize acetylene and butadiene to give soluble, linear, random copolymers in high yield. Toluene and xylene were the preferred solvents for the copolymerization. The catalyst activity and copolymer composition were influenced by the Al/Ni molar ratio, polymerization temperature, polymerization time, and conditions of preparation of catalyst. |
