    Abstract: A rubber-modified styrene resin containing a rubbery polymer as dispersed particles, wherein the continuous phase has a weight-average molecular weight (MwL) of 180,000 to 280,000 and the weight-average molecular weight and the 1-cm drawdown time (sec) for a rubber-modified styrene resin sheet satisfy the relationship [1-cm drawdown time (sec)] > (MwL/10 ) - 4.0; an effective process for producing the resin; and a rubber-modified styrene resin sheet obtained by forming the resin. The rubber-modified styrene resin has so high thermoforming stability that a sufficiently long time for thermoforming can be ensured. It is suitable for use in forming into a sheet. The rubber-modified styrene resin sheet has excellent thermoforming stability.

    Abstract: 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.
