Non-delaminating resinous compositions are prepared by blending at least one polyetherimide, at least one liquid crystalline polyester in an amount to provide lower melt viscosity, and a compatibilizing amount of at least one polyepoxy compound. The compositions may also contain a minor proportion of at least one non-liquid crystalline polyester such as poly(ethylene terephthalate) or poly(ethylene 2,6-naphthalenedicarboxylate).

Compatibilized blends of polyetherimides and liquid crystalline

Semi-crystalline blow moldable polyester compositions formed by melt blending a mixture consisting essentially of a poly(butylene terephthalate, an ethylene copolymer containing epoxide groups, and an ionomer obtained by neutralizing with Na.sup.+ or K.sup.+.

Thermoplastic blow moldable polybutylene terephthalate compositions

Semi-crystalline blow moldable polyester compositions formed by melt blending a polyester, an ethylene copolymer containing epoxide groups, a methyl methacrylate copolymer containing epoxide groups, an ionomer obtained by neutralizing with Na+ or K+ and optionally another polyester.

Thermoplastic blow moldable polyester compositions

Semi-crystalline blow moldable polyester compositions, formed by melt blending a polyester, an ethylene copolymer containing epoxide groups, an ionomer obtained by neutralizing with Na+ or K+ and optionally a second polyester.

Thermoplastic blow moldable polyethylene terephthalate compositions

A blow moldable composition of a polyether, an epoxide polymer, a source of catalytic cations, and a fibrillatable tetrafluoroethylene polymer.

Blow molding polyester compositions

A blow moldable composition of a polyester, an epoxide polymer and a source of catalytic cations.

Polyester compositions for blow molding

A composition consisting essentially of (A) 65 to 99 percent by weight of a polymer consisting essentially of 76 to 85 percent by weight acrylonitrile polymerized units and 24 to 15 percent by weight polymerized units of at least one aromatic olefin containing 8 to 14 carbon atoms, said polymer having a melt viscosity of 10.sup.4 to 10.sup.6 poises at 220.degree.C. and an inherent viscosity of from 0.3 to 1.0 deciliter per gram and (B) 1 to 35 percent by weight of grafted rubber, said grafted rubber consisting essentially of 30 to 50 percent by weight of a graft polymer consisting essentially of 61 to 85 percent by weight acrylonitrile polymerized units and 39 to 15 percent by weight polymerized units of at least one aromatic olefin containing 8 to 14 carbon atoms, and 50 to 70 percent by weight rubber; said composition having a carbon dioxide permeability of less than 0.045 barrer; and shaped articles made therefrom.
