Abstract
Abstract Organic phosphites are provided having at least one 2,2,6,6-tetramethyl piperidyl substituent attached at the 4-position to phosphorus through oxygen, and at least one polyol or polyphenol group, which are superior light and heat stabilizers for organic polymeric mterials such as polyethylene, polypropylene, polyvinyl chloride, acrylonitrile-butadiene-styrene terpolymers, polyamides, polystyrene, and similar polymers.
