- (I) about 1-99 parts by weight of a polycarbonate containing halobis(phenyl)ethylene carbonate units of the formula: ##STR10## where independently each R.sup.1 is hydrogen, C.sub.1-4 alkyl or phenyl, and having an intrinsic viscosity of 0.38 to 0.7 deciliters per gram, and
- (II) about 99-1 parts by weight of a poly(1,4-alkylene terephthalate) having an intrinsic viscosity of 0.5 to 1.3 deciliters per gram.
- 2. The claim 1 composition where each R.sup.1 is a hydrogen.
- 3. The claim 2 composition where the terephthalate is poly(1,4-butylene terephthalate).
- 4. The claim 1 composition containing about 1-50 parts of a polycarbonate containing halobis(phenyl)ethylene carbonate units, and about 99-50 parts of poly(1,4-butylene terephthalate).
- 5. The claim 1 composition containing about 25-90 parts by weight of a polycarbonate containing halobis(phenyl)ethylene carbonate units, and about 75-10 parts by weight of a poly(1,4-butylene terephthalate).
