Thermoplastische Massen zur Herstellung von gegen Hitze, Licht und Alterung stabilisierten Formkoerpern aus kristallinen Polyolefinen

摘要

A crystalline polyolefin is stabilized with a long chain aliphatic thioester, an hydroxybenzotriazole and a phenol. The thioester may be a thiodipropionate or a thiodiglycolate, and the phenol may be a condensate of an alkyl phenol with an aldehyde or a ketone or thiobis - 6 - #t - Bu - m - cresol. Optional ingredients include calcium stearate. Specification 960,012 is referred to.
