Transition And Organic Metals Composition Catalysts For Addition Polymerization
(AREA)
Abstract
The method of polymerizing ethynylene, which consists of contacting ethylene with a catalyst that is formed by mixing one of the salts of the group comprising the bis (cyclopentadienyl) titanium salts, the bis (cyclopentadienyl) zirconium salts and the salts of bis (cyclopentadienyl) vanadium, in which the cyclopentadinyl moiety is chosen from the group consisting of the cyclopentadienyl and the alkylcyclopentadinyl radicals, with an alkyl metal compound selected from the group comprising the metals belonging to groups ia, ii-a, ii-b and iii-a of the periodic table.
