Patent number: 6815500Abstract: The invention concerns a method for preparing a composition comprising a vinylaromatic polymer enclosing rubber nodules. The invention is characterised in that it includes a step for polymerising at least one vinylaromatic monomer in the presence of rubber, a polymerisation initiator and a stable free radical, said step being such that [FSFR×(SFR)]: [FAMO×(AMO)] range from 0.05 to 1, FFSR and FAMO representing the functionality of the stable free radical and the initiator respectively and (SFR) and (AMO) representing the molar quantities of the stable free radical and the initiator respectively, The final composition is particularly resistant to shock and/or shiny.Type: GrantFiled: August 31, 2001Date of Patent: November 9, 2004Assignee: AtofinaInventor: Jean-Marc Boutillier

Patent number: 6809165Abstract: A process for the preparation of polymers is described, wherein at least one first ethylenically unsaturated monomer is subjected to a free radical polymerization in the presence of stable free radicals or sources of stable free radicals and of a compound having at least one free thiol group to give a polymer, and wherein the molar ratio of compound having a free thiol group to stable free radicals is from 0.05 to 1.1. The polymerization rate is substantially increased by the compound having a free thiol group.Type: GrantFiled: September 27, 2002Date of Patent: October 26, 2004Assignee: BASF AktiengesellschaftInventors: David Christie, Sylke Haremza, Susanne Brinkmann-Rengel, Roman Benedikt Raether

Patent number: 6777499Abstract: The present invention relates to multiblock interpolymers having the following symmetric structures and processes for their preparation: Y-X-Y, wherein Y represents a block of a random copolymer of conjugated diene and monovinyl aromatic monomer; and X represents a block of butadiene homopolymer, a block of isoprene homopolymer, or a block of butadiene/isoprene copolymer, and processes for the preparation thereof. The present multiblock interpolymers have in the same molecule both a rubber block of random copolymer of conjugated diene and monovinyl aromatic monomer and a rubber block selected from blocks of butadiene homopolymer, isoprene homopolymer and butadiene/isoprene copolymers, and hence possess excellent properties of the both two kinds of rubbers, and can be used widely as integrated rubber materials with excellent property balance, the present processes can simply prepare the above integrated rubber material in situ in a single reactor.Type: GrantFiled: May 20, 2002Date of Patent: August 17, 2004Assignees: China Petroleum & Chemical Corporation, Research Institute of Beijing Yanshan Petro Chemical Co.
