Abstract (en)
[origin: US4111899A] This invention relates to thermoplastic resin compositions containing an organo-phosphorus compound. The organo-phosphorus compound has one of the formulas I. (R1) (R2) P(=X)a - P(=X)a (R1) (R2) II. (P - R1)n III. (R1) (R2) P (=X)a - P(R3) - P(=X)a (R1) (R2) wherein a is independently 0 or 1, n is 3 to 6, X is oxygen or sulfur, R1, R2 and R3 are independently dialkylamino, alkoxy, aryloxy, alkyl, aryl, alkaryl, aralkyl, or R1 and R2 taken with the phosphorus atom represent a cyclic structure having only carbon, phasphorus and oxygen atoms in the cyclic structure. The thermoplastic resin compositions of this invention are resistant to discoloration.
