Certain metal compounds such as antimony oxide and magnesium oxide are used to enhance the notched Izod impact resistance of molded objects made from selected polyamide copolymer compositions comprised of polyepsiloncaprolactam (nylon-6) or polyhexamethyleneadipamide (nylon-66) and preferably ethylene/ethyl acrylate and ethylene/acrylic acid copolymers.

High impact molding compositions

A polyethylene terephthalate composition comprising the salt of a dimer acid, trimer acid or the salt of a mixture of dimer and trimer acid. The dimer and/or trimer acids are neutralized with a Group IA metal cation, preferably sodium. The composition can contain a filler, plasticizer, impact modifier and/or a polyepoxide.

Nucleation agents for crystalline polymers

A laminate structure comprising at least one layer of a polyamide and at least one layer of polyethylene containing from 0.1 to 20 percent based on the weight of the polyethylene of oxidized high density polyethylene.

Polyamide-polyethylene laminates

A laminate structure having at least one layer of a polyamide containing from 0.001 to 1.0 parts, based on the weight of the polyamide, of a copper cation containing material. The polyamide layer is contiguous to at least one opposing layer. The opposing layer contains an effective amount of functional groups selected from the group consisting of acid groups, metal salts of the acid, acid anhydrides, carbonates and mixtures thereof.

Polyamide laminates containing copper salts

Disclosed is a method for coating substrates with a stress-crack resistant coating of a fluoropolymer and a polyfunctional compound having two or more allyl groups such as triallylcyanurate or triallylisocyanurate wherein the fluoropolymer is a polymer comprised of ethylene, chlorotrifluoroethylene or tetrafluoroethylene and optionally a termonomer such as 3,3,3-trifluoro-2-trifluoromethyl propene. The ingredients are homogeneously blended and applied to the substrate which is maintained at an elevated temperature to allow flow-out of the coating mixture thereby forming a stress-crack resistant coating.

Method for applying stress-crack resistant fluoropolymer coating

Improved multi-layered laminates having at least one layer of a polyamide such as polyepsiloncaprolactam containing an excess of terminal amine groups and at least one layer, opposing the polyamide layer, containing a polymer having pendent carboxylic acid groups, their salts, carbonates, or acid anhydrides.

Polyamide laminates

Stabilized fluoropolymer compositions comprising a polymer from about 40 to 60 mol percent ethylene, about 60 to 40 mol percent chlorotrifluoroethylene and optionally about 0.1 to 10 mol percent of a fluorinated termonomer selected from the group consisting of 3,3,3-trifluoro-2-trifluoromethyl propene, a vinyl monomer which is free of telogenic activity and which provides a side chain having at least two carbon atoms, the side chain being aromatic or having its elements bonded by a single bond only, and mixtures thereof, and as a stabilizing agent, a member selected from the group consisting of epoxy resins, mixtures of tribasic lead sulfate and bisphenol A, and mixtures of the epoxy resin, tribasic lead sulfate and bisphenol A.

Stabilized ethylene-chlorotrifluoroethylene polymers exhibiting reduced

Solutions of a copolymer of about 55 to 95 mol percent chlorotrifluoroethylene and about 45 to 5 mol percent ethylene in an organic solvent. The solutions may optionally contain an organic silane, preferably an aminosilane.

Solutions of ethylene-chlorotrifluoroethylene copolymers

Stress-crack resistant terpolymers of from about 40 to 60 mol percent ethylene, about 60 to 40 mol percent of a halogenated comonomer selected from the group consisting of tetrafluoroetylene, chlorotrifluoroethylene and mixtures thereof and about 0.1 to 10 mol percent of a termonomer selected from the group consisting of 3,3,3-trifluoro-2-trifluoromethyl propene, a vinyl monomer which is free of telogenic activity and which provides a side chain having at least two carbon atoms, the side chain being aromatic or having its elements bonded by a single bond only, and mixtures thereof, and containing high and low molecular weight components such that: ##EQU1## WHEREIN X.sub.i represents the weight fraction of each high molecular weight component i;

Stress-crack resistant ethylene-perhaloethylene terpolymers

Stress-crack resistant copolymers of from about 40 to 60 mol percent ethylene and 60 to 40 percent of a halogenated comonomer selected from the group consisting of tetrafluoroethylene and chlorotrifluoroethylene and mixtures thereof and containing high and low molecular weight components such that: ##EQU1## WHEREIN X.sub.i represents the weight fraction of each high molecular weight component i;
