Paragraph 0012; 0013; 0015, (2018/04/03)
The invention provides a novel phosphorus-containing anti-oxidant-3-distearate pentaerythritol diphosphite. The product is mainly used as an auxiliary anti-oxidant for polyethylene, polypropylene, polyvinyl chloride, ABS resin, polyester and other various synthetic resins. The product has protruding effects for preventing oxidation, improving color and the like; the product has higher heat stability, weather resistance, hydrolysis resistance stability, and good processing stability. The product has a pentaerythritol structure and a high molecular weight characteristic, has functions for lubrication, plasticizing and stabilization, and the product is widely applied to polymeric materials which require high temperature processing. The structure of the product does not have alkylphenol, the product is safe and nontoxic, and the product accords with newest market regulations and development trend. The product can be applied to packaging materials for foodstuff (TITLE 21 CFR.178.2010). Theproduct is mainly suitable for production and processing of auxiliary agents for compounding ABS, PS, HIPS, NBR, SBS, PP, PE, LLDPE, PVC, PC, PA, PET, UP, amide fiber, polyester fiber, an adhesive, paint, and printing ink; and compounding a calcium zinc stabilizing agent.
