Carbonate polymers containing at least one terminal group represented by the general formula ##STR1## wherein R and R.sup.1 are independently selected from hydrogen and monovalent hydrocarbon radicals.

Polycarbonate end capped with vinylene carbonate compound

Polymers containing at least one terminal group represented by the general formula ##STR1## wherein R and R.sup.1 are independently selected from hydrogen and monovalent hydrocarbon radicals.

Aromatic polycarbonate containing thieno-2-one-5,5-dioxide terminal

Thermoplastic composition exhibiting improved hydrolytic stability comprised of in physical admixture at least one aromatic carbonate polymer and an effective hydrolytic stabilizing amount of at least one compound represented by the general formula ##STR1## wherein R and R.sup.1 are independently selected from hydrogen, monovalent hydrocarbon radicals, and monovalent hydrocarbonoxy radicals.

Hydrolytically stabilized polycarbonates

This invention relates to novel thermoplastic compositions that are based on an aromatic polycarbonate in admixture with impact modifying quantities of a modified aromatic polycarbonate to which are grafted polymers of a long chain alkenyl compound.

Composition comprising graft polycarbonates

A novel thermoplastic composition is disclosed which is based on polyolefin and a block copolymer of a dihydric phenolic monomer, a carbonate precursor and a polyphenylene oxide resin. These compositions may be used as molding resins and have better compatibility than admixtures of aromatic polycarbonate and a polyolefin.

Composition comprising a polyolefin and a block copolymer of a dihydric

Novel carbonate polymers comprised of the reaction product of a dihydric phenol, a carbonate precursor, and at least one imide selected from the group of compounds represented by the formulae ##STR1##

Carbonate copolymers prepared from imide reactants

Thermally stable polycarbonate compositions are obtained by admixing with a high molecular weight aromatic polycarbonate resin a stabilizing amount of a bisphosphite.
