High impact polystyrenes and related monovinyl aromatic polymers generally have either a high modulus or good resistance to environmental stress cracking. The present invention is directed at polymeric materials having both a high modulus and good resistance to environmental stress cracking thus enabling the down gauging of parts, and or the use of the materials in new applications. The invention is predicated on the use of one or more, or even all of the following features: a high molecular weight matrix polymer, reduced concentration of elastomeric polymer, or methods that result in large rubber particle size.

High impact polystyrene having high modulus and resistance to environmental stress cracking

High impact polystryene having high modulus and resistance to environmental stress cracking

A method for processing a thermoplastic material that comprises a microwave-sensitive polymeric region, wherein the method includes exposing the microwave-sensitive polymeric region to microwaves; wherein the exposing results in an increase in the temperature of the polymeric region; and processing the thermoplastic material is disclosed.

Use of microwave energy to selectively heat thermoplastic polymer systems

A microwave-sensitive thermoplastic composition that includes a microwave-receptive additive; and a thermoplastic polymer; wherein the microwave-receptive additive is selected from the group consisting of sepiolite clay, molecular sieves formed from ammonium ion salts or hydrogen ion salts, aluminophosphates, silicoaluminophasphates, silicotitanates, organo-modified clays, molecular sieves or zeolites having a caged organic microwave receptive material, and combinations thereof.

Additives for the use of microwave energy to selectively heat thermoplastic polymer systems

A method for melt-processing a polymer of a monovinyl aromatic compound, such as styrene, is disclosed. The method may include heating a polymer of a monovinyl aromatic compound volumetrically with microwave energy, wherein the polymer of a monovinyl aromatic compound includes: a discontinuous rubber phase; and a continuous poly(monovinyl aromatic) phase comprising up to 49 weight percent of at least one of an acrylate comonomer and a vinyl cyanide comonomer.
