Patent ID: 8426537

Claim:
A solid catalyst component for olefin polymerization produced by contacting with each other: (a) a solid component that comprises magnesium, titanium, a halogen, and an electron donor; (b) an aminosilane compound shown by formula (1) R 1 n Si(NR 2 R 3 ) 4-n (1) wherein each R 1 is independently a linear or branched alkyl group having from 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl group, a vinyl group, an allyl group, an aralkyl group, a substituted or unsubstituted phenyl group, a substituted or unsubstituted benzyl group, or a substituted or unsubstituted naphthyl group, each R 2 is independently a hydrogen atom, a linear or branched alkyl group having from 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl group, a vinyl group, an allyl group, or an aralkyl group, each R 3 is independently a linear or branched alkyl group having from 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl group, a vinyl group, an allyl group, or an aralkyl group, R 2 and R 3 optionally bond to form a ring, n is an integer from 0 to 3, and at least one NR 2 R 3 group is a secondary amino group comprising an N—H bond; and (c) an organosilicon compound of formula (2-A) [CH 2 ═CH—(CH 2 ) t ] q SiR 4 4-q (2-A) wherein each R 4 is independently a hydrogen atom, an alkyl group having from 1 to 20 carbon atoms, a cycloalkyl group, an aryl group, a vinyl group, or a halogen atom, 1 is an integer from 0 to 5, and q is an integer from 1 to 4, with the proviso that if q is 1, at least one R 4 is an alkyl group having from 2 to 20 carbon atoms, a cycloalkyl group, an aryl group, a vinyl group, or a halogen atom.
