PROCESS FOR PRODUCING MODIFIED PARTICLE, CARRIER OR CATALYST COMPONENT FOR ADDITION POLYMERIZATION, PRE-POLYMERIZED CATALYST COMPONENT THEREFOR, CATALYST THEREFOR, AND ADDITION POLYMER

摘要

Production of modified particles, a carrier or a catalyst component for addition polymerization involves preparing a product by contacting a Group 13 element compound (I) (e.g. trialkyl aluminum) with a Group 15 or 16 element compound (II) (e.g. alcohol), then contacting the product with a Group 15 or 16 element compound (III) (e.g. water) in presence of particles. - Production of modified particles, a carrier or a catalyst component for addition polymerization involves preparing a product by contacting a Group 13 element compound of formula M1(L1)3 (I) with a Group 15 or 16 element compound of formula (R1)t-TH (II), then contacting the product with a Group 15 or 16 element compound of formula (R2)t-2-TH2 (III) in presence of particles. - M1 = Group 13 element; - L1 = H, hydrocarbyl or halo; - R1 = electron withdrawing residue or group containing an electron withdrawing residue; - R2 = optionally halogenated hydrocarbyl; - T = non-metallic Group 15 or 16 element; and - t = valency of T (i.e. 2 or 3). - Independent claims are included for: - (1) the preparation of an addition polymerization catalyst (APC1), by contacting modified particles (A) obtained by the above process with a transition metal compound (B) and optionally an organo-aluminum compound (C); - (2) the preparation of a prepolymerized catalyst component (PPCC) or catalyst (PPC) for addition polymerization, by preparing a primary catalyst by contacting (A) with (B) and optionally (C), then prepolymerizing an olefin in presence of the primary catalyst; - (3) the preparation of an addition polymerization catalyst (APC2), by contacting the above PPCC with (C); and - (4) the production of an addition polymer, by polymerization of appropriate monomer(s) in presence of APC1, APC2 or PPC as catalyst.
