Abstract: A high impact polystyrene reactor system includes a first continuously stirred tank reactor. The first continuously stirred tank reactor includes an inlet configured to receive (i) at least one vinyl aromatic monomer, (ii) an elastomer, and (iii) a free radical initiator; and an outlet configured to convey a first reactor effluent. In addition, the high impact polystyrene reactor system includes a second continuously stirred tank reactor. The second continuously stirred tank reactor includes an inlet in fluid communication with the first continuously stirred tank reactor outlet and configured to receive (i) a portion of the first reactor effluent from the first continuously stirred tank reactor, (ii) at least one vinyl aromatic monomer, (iii) an elastomer, and (iv) a free radical initiator; and an outlet configured to convey a portion of a second reactor effluent comprising high impact polystyrene. Further, the high impact polystyrene reactor system includes a conduit for establishing a recirculation stream between the second reactor and the first reactor. The recirculation stream comprises another portion of the second reactor effluent.

Abstract: A vessel header includes lateral flow tubes arranged in a parallel configuration. The lateral flow tubes enter the vessel header through alternating vessel header penetrations with a single vessel header penetration per lateral flow tube. Each lateral flow tube has a perforated section within the vessel header having a non-circular cross-section having the shape of a circular sector, an elliptical sector, or an irregular quadrilateral. A method includes passing a molten polymer through the lateral flow tubes of the vessel header. The molten polymer exits the lateral flow tubes as strands through perforations in the lateral flow tubes within the vessel header. The method includes obtaining devolatilized polymer.

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.

Abstract: Disclosed is a polystyrene based polymer/layered compound nanocomposite for injection blow molding or injection stretch blow molding of articles. The nanocomposite can reduce shrinkage and warpage to the preform during the reheating process compared to neat polystyrene. The incorporation of layered compounds can increase the processability of PS preforms, help improve heating efficiency, and improve bottle mechanical properties. The layered compound can be treated with chemicals or compounds having an affinity with the styrene monomer or polystyrene, thus producing a treated layered compound having an affinity with the styrene monomer or polystyrene. The monomer and the layered compound can be combined prior to polymerization. The polymer and layered compound can be combined by solution mixing in a solvent. The layered compound can also be incorporated into the mixture by compounding a polymer product with the layered compound, or the combination of any of the above three approaches
