Lubricated thermoplastic styrene polymer - contg hydrogenated styrene oligomer

摘要

Title polymer moulding materials contain 1-10 esp. 2-6 wt.% hydrogenated styrene oligomer with an average mol. wt. of 300-30,000 (400-8,000) esp. 500-5,000. The polymer can be injection moulded at relatively low temps., without a considerable lowering of the resistance to thermal deformation. The oligomer does not cause yellowing, and can be added to the polymsn mixt. without causing a lowering of the mol. wt. of the polymer.
