Abstract
There is disclosed a method for homo-polymerizing cis-1,3-pentadiene or copolymerizing it with trans-1,3- pentadiene to prepare cis-1,4 polypentadienes. Other conjugated diolefins, including butadiene, isoprene, 2-ethyl- 1,3-butadiene and 2-methyl-1,3- pentadiene also may be copolymerized with the cis-1,3-pentadiene isomer to prepare elastomeric copolymers. There is also disclosed a method for the copolymerization of isoprene with trans-1,3-pentadiene. The polymerization catalyst employed in all of these polymerizations is a ternary catalyst system comprising (a) an organometallic compound selected from aluminum trialkyls, magnesium dialkyls and zinc dialkyls, (b) a soluble chromium compound selected from chromium salts of organic acids containing from 2 to 20 carbon atoms, organic complex compounds of chromium containing tridentate ligands and pi -bonded organochromium compounds, and (c) a member selected from dialkyl hydrogen phosphites, diaryl hydrogen phosphites and tris(2-chloro ethyl) phosphite.
