Abstract
Disclosed is composition comprising an admixture of (A) from 99 to 1 weight percent, based on the weight of the admixture, of a copoly(arylene sulfide) corresponding to the structure [(--A--S--).sub.1-x (--A--S--S--).sub.x ].sub.n wherein A is a divalent substituted or unsubstituted aromatic radical, x is in the range of 0.5 to 0.001 and n is at least 25, and (B) from 1 to 99 weight percent, based on the weight of the admixture, of an bisphenol-A polycarbonate having an inherent viscosity of at least 0.3.
Claims5
A composition comprising an admixture of
- (A) from 99 to 1 weight percent, based on the weight of the admixture, of a copoly(arylene sulfide) corresponding to the structure [(--A--S--).sub.1-x (--A--S--S--).sub.x ].sub.n
- wherein A is a divalent substituted or unsubstituted aromatic radical, x is in the range of 0.5 to 0.001 and n is at least 25, and
- (B) from 1 to 99 weight percent, based on the weight of the admixture, of an bisphenol-A polycarbonate having an inherent viscosity of at least 0.3.
The composition of claim i wherein the divalent aromatic radical is p diiodobenzene, m-diiodobenzene, p,p'-diiodobiphenyl, p,p'-diiododiphenyl ether or 2,6 diiodonaphthalene.
A composition comprising an admixture of
- (A) from 85 to 15 weight percent, based on the weight of the admixture, of a copoly(phenylene sulfide) corresponding to the structure
