    摘要: The invention relates to mixed esters of phosphorous or phosphoric acid having on the one hand open chain polyalcohols and on the other hand long chain alkyl compounds with activated hydrogen, for example, alcohols, mercaptans and amines. The compounds are suitable as light and heat stabilizers for polyolefins and for chlorine-containing thermoplastic compositions and are furthermore distinguished by a high resistance to hydrolysis.

    摘要: The present application relates to storage-stable plastics additives which are prepared by cooling a mixture of 99.9 to 10% by weight of molten additive material and 0.1 to 90% by weight of crystalline additive material after a shaping process. The shaping process is carried out by forcing the mixture out of a tool provided with die openings, and cooling can be carried out on a cooled conveyor belt. Even after prolonged storage and/or handling, these plastics additives remain free-flowing and do not stick.
