Claims6
A composition comprising
- a. a high molecular weight polymer having as a repeating unit an aromatic carbonate ##STR2## said polymer endcapped with
- XR
- wherein X is derived from an organic moiety having a single substituent reactive with the acidic hydrogen of a phenol or the chlorine of phosgene and R is selected from the group consisting of the hydrocarbyl portion of the following acids or acid chlorides;
- stearic, isostearic, palmitic, myristic, lauric, pelagronic, caproic, caprylic, oleic, linoleic and abietic in admixture with
- b. about one to about ten parts of a polyolefin selected from the group consisting of polyethylene or polypropylene, said parts per 100 parts by weight of the polymer of section a.
