Process for the polymerization of olefins using group 4 metallocenes as catalysts |
| abstract |
A process for the preparation of a propylene random copolymer comprising the polymerization of propylene and at least one C2-10 alpha-olefin (especially ethylene) in the presence of a catalyst; wherein said catalyst comprises: (i) a complex of formula (III)**Formula** wherein M is Zr or Hf; each R1 is CH2-Ph, CH1-C(R3)3-q(H)q in which R3 is a C1-6 alkyl group or two R3 groups together form a C3-7 cycloalkyl ring in which said ring is optionally substituted with a C1-6 alkyl group and q can be 1 or 0; L is SiR6 2; R6 is C1-10 alkyl, C6-10 aryl, C7-12 alkylaryl, or C7-12 arylalkyl; each X is a hydrogen atom, OR, a halogen atom, or an R group; R is C1-10 alkyl each R4 is H or C1-3 alkyl; n is from 0 to 2; p is from 0 to 2; each R5 is C1-10 alkyl and each R18 is C1-6 alkyl; and wherein the two ligands forming the complex are identical; and (ii) a cocatalyst comprising an organometallic compound of a Group 13 metal. |
