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 Si-H bond-contg. chlorosilane cpd., a Ti halide and one or more kinds of S-, O- and N-contg. heterocyclic carboxylic acid esters.
CONSTITUTION: An olefin is suspension polymerized in an org. solvent by making combined use of a solid catalyst component obtd. by reaction pulverizing or pulverizing or pulverizing a solid reaction product of an org. Mg cpd. of formula R1MgX (where R1 is 1W20C alkyl or aryl and X is halogen) and a Si-H bond-contg. chlorosilane cpd. of formula I (where a>0, b>0, a+b≤4 and R is -HC), TiCl3 or TiCl4, and one or more kinds of S-, O- and N-contg. heterocyclic carboxylic acid esters, and a component contg. an org. Al cpd. and one or more kinds of S-, O- and N-contg. heterocyclic carboxylic acids. Thus, a highly stereoregular polymer with high bulk density, good grain size and little scale deposition can be obtd. with high catalytic efficiency.
