Abstract

PURPOSE: To improve the weather resistance and discoloration resistance of a polymer remarkably, by compounding a specific phosphite compound as a stabilizer.
CONSTITUTION: 100pts.wt. of a polymeric compound is compounded with 0.005W 5.0pts.wt. of a phosphite compound selected from (A) a compound of formula I [R1 and R2 are H, alkyl, aryl or group of formula II (R3 and R4 are alkyl, aryl, alkenyl, etc.; R5 is H, alkyl, aryl, etc.); X is group of formula III or IV; R6 and R7 are same as R1 and R2, and at least one of R1, R2, R6 and R7 is group of formulaII; Y1 and Y2 are polyhydric alcohol or polyhydric phenol; a is 0W10], e.g. the compound of formula V, and (B) a compound of formula VI (when d is 0, B is group of formula III or IV, and when d is 1, B is group of formula VII; R9 and R12 are same as R1; at least one of R9, R12, R6 and R7 is group of formula II; A is residue of polyhydric alcohol or polyhydric phenol, and when d is 0, it is trihydric or more, and when d is 1, it is tetrahydric or more), e.g. the compound of formula VIII.
