摘要： According to the present invention there are provided improved non-compatibilized blends of (A) a rubber modified monovinylidene aromatic polymer and a minor amount of (B) an ethylene polymer having a density in the range of from about 0.87 to about 0.98 grams per cubic centimeter (g/cc) as measured by ASTM D 792 and (C) optional additives and stabilizers. These improved blends are specially adapted and suited for use in stretch blow molding processes. They provide improved combinations of improved opacity, controlled gloss surface appearance, haptics and physical properties and improved processes for producing stretch blow molded and thermoformed articles at relatively high production rates and reduced expense. The present invention provides the makers of many types of containers with options for improved packaging efficiency meaning that less weight and cost of resin is required to make a given size of container, providing obvious advantages in terms of raw material costs and reduced container shipping weight as well as containers with improved combinations of opacity, controlled gloss surface aesthetics and physical properties.
