MONOVINYL AROMATIC POLYMER COMPOSITIONS WITH A NOVEL COMBINATION OF STIFFNESS AND STRESS CRACK RESISTANCE |
摘要 |
A rubber modified polystyrene composition that includes the reaction product formed by polymerizing a monomer mixture containing at least 75 weight percent of one or more monovinylaromatic monomers in the presence of rubber particles to form a dispersion of rubber particles in a vinyl aromatic polymer. The dispersed rubber particles have an average particle diameter of from about 6 to about 10 microns. The composition has a gel content of from about 28% to about 36% by weigh. The composition has a swell index of less than 13 and contains no more than 2 wt.% of plasticizers. The present composition can be used as a refrigerator liner material. The liner material can be down gauged while maintaining desirable performance characteristics.
