What is Effect of substituents at position 4 on the stereospecific polymerization of 1,3-diolefins. Polymers with a 1,2 isotactic structure from 4-methyl-1,3-pentadiene about?
Abstraet--4.Methyl-l,3-pentadiene has been polymerized by heterogeneous catalysts from AI(C2Hs) 3 and either TIC14, TIC13 or VCI3, to give polymers having almost exclusively 1,2 units, and showing crystallinity attributable to 1,2 isotactic sequences. Homogeneous systems from AI(C2Hs)3 and either a titanium tetraalkoxide or a vanadyl trialkoxide yield from the same monomer polymers, which, although almost 100 per cent 1,2, are amorphous by X-ray examination. Infra-red and X-ray analyses indicate that the 1,2 isotactic polymers of 4-methyl-l,3-pentadiene exist in two crystalline modifications. The different results obtained from 4-methyl-l,3-pentadiene as compared with butadiene in the polymerization by each of the above systems, are interpreted on the basis of steric effects caused by the methyl groups on position 4. \* X-ray structure has been studied by Prof. I. W.
