| titleOfInvention | Olefin polymerization catalyst |
| abstract | PURPOSE: To provide the title catalyst of high catalytic efficiency giving a polymer of high stereoregularity which catalyst contains a component obtd. by reacting or pulverizing a solid reaction product of an org. Mg cpd. and a halogen cpd., a Ti halide and one or more kinds of S-, O- and N-contg. heterocyclic carboxylic acid esters. n CONSTITUTION: The catalyst consists of a component obtd. by reaction pulverizing or pulverizing a reaction product of an org. Mg cpd. of formula I and a halogen cpd. of formula II, TiCl 3 or TiCl 4 , and one or more kinds of S-, O- and N-contg. hetercyclic carboxylic acid esters, and of a component contg. an org. Al cpd. and one or more kinds of the above esters. In the formula, α≥0, p≥0, q≥0, r≥0, s≥0, ΖpWs = mα+2β, M is a IWIII group metallic element, m is the valence of M, each of R 1 and R 2 is -HC, each of X and Y is OR 3 , OSiR 4 R 5 R 6 , NR 7 R 8 or SR 9 , each of R 3 WR 8 is H or -HC, R 9 is -CH, L is B, Hg, Te and a IVb or Vb group element other than C and N, J is halogen, R 0 is -HC, a is the valence of L and 0<j≤a. n COPYRIGHT: (C)1979,JPO&Japio |
