摘要：
Thermoplastic resin compositions are heat stabilized by the addition of 0.01 to 1.0 percent by weight of an organo-phosphorus compound having one of the formulas(R.sub.1) (R.sub.2) P (.dbd. X).sub.a -- P(.dbd. X).sub.a (R.sub.1) (R.sub.2) I(p -- r.sub.1).sub.n II(r.sub.1) (r.sub.2) p (.dbd. x).sub.a -- P(R.sub.3) -- P(.dbd. X).sub.a (R.sub.1) (R.sub.2) IIIwherein a is independently 0 or 1, n is 3 to 6, X is oxygen or sulfur, R.sub.1, R.sub.2, and R.sub.3 are independently dialkylamino, alkoxy, aryloxy, alkyl, aryl, alkaryl, aralkyl, or MO where M is an alkali metal, or R.sub.1 and R.sub.2 taken with the P atom represent a cyclic structure.
