ABSTRACT:
There is a demand for very clear tough polymers or polymer blends, particularly in the packaging industry. Crystal polystyrene is clear but lacks toughness. HIPS is tough but lacks the required clarity. Blends of styrene-ester polymers with a very small amount of HIPS do provide a very clear tough polymer alloy.
