摘要：The invention pertains generally to an improved polymer composition whichcontains at least one polymeric polyphosphite or copolymeric polyphosphite additivecontaining no alkylphenols. Alkylphenol-free polymeric polyphosphites offer distinctadvantages over conventional phosphite technology in rubbers and rubber compounds.Polymeric polyphosphites offer improved performance in regards to the prevention ofcolor formation during high temperature processing and NOx aging.
