The abstract was not in accordance with PCT Rule 8.1 (b) because it was more than 150 words in length. The abstract has been established by this Authority to read as follows: A process for producing high impact polystyrene including feeding at least one vinyl aromatic monomer; an elastomer, and a free radical initiator to a first linear flow reactor to form a reaction mixture. Polymerizing the reaction mixture in the first linear flow reactor to a point below the point at which phase inversion occurs to produce a first polymerization mixture and feeding the first polymerization mixture from the first linear flow reactor to a second linear flow reactor. Polymerizing the reaction mixture in the second linear flow reactor to at least a phase inversion point of the mixture to produce a second polymerization mixture and feeding the second polymerization mixture from the second linear flow reactor to at least a third linear flow reactor for post.inversion polymerization of the second polymerization mixture.

Abstract:
Blends of syndiotactic 1,2-polybutadiene and rubbery elastomers are prepared by a process that includes polymerizing 1,3-BD monomer into syndiotactic 1,2-polybutadiene within a rubber cement of at least one rubbery elastomer by using a catalyst composition that is formed by combining a hydrogen phosphite with a Cr-containing compound and an organomagnesium compound or with a Mo-containing compound and an organoaluminum compound.
Abstract:
An expandable polymer composition in the form of beads is manufactured by a seed polymerisation process, wherein an advantageous setting of the molecular weight and thus the glass transition temperature of the polymer composition is possible while allowing a reduced content of blowing agent within the expandable polymer composition.
Abstract:
The present invention is crosslinked polymer particles, prepared from a free-radical activated reaction of an unsaturated coagent and low molecular weight hydrocarbons or certain polymers. This invention allows particles to be made from mixtures of coagents and saturated compounds. The invention is also a process for preparing crosslinked polymer particles.
