Blended polymer compositions are described which comprise:

Polyphenylene ether-polyetheramide blends

Copolymer-containing compositions are prepared by the reaction of an epoxytriazine-capped polyphenylene ether with another polymer containing carboxy end groups, especially a polyester. The compositions have excellent properties and find utility as molding compositions and as compatibilizers for blends of similar polymers. Suitable epoxytriazine-capped polyphenylene ethers may be prepared by reaction of a polyphenylene ether with an epoxychlorotriazine such as diglycidyl chlorocyanurate, n-butyl glycidyl chlorocyanurate or mesityl glycidyl chlorocyanurate.

Compositions comprising polyphenylene ether-polyester copolymers from

A method for the production of functionalized polyphenylene ether by contacting crude polyphenylene ether with an aqueous base and subsequently adding substituted chlorotriazine such as butyl glycidyl chlorocyanurate or mesityl glycidyl chlorocyanurate.

Process for functionalizing polyphenylene ether with substituted

Copolymer-containing compositions are prepared by the reaction of an epoxytriazine-capped polyphenylene ether with another polymer containing amine end groups, especially a polyamide, under intimate blending conditions. The compositions have excellent properties and find utility as molding compositions and as compatibilizers for blends of similar polymers. Suitable epoxytriazine-capped polyphenylene ethers may be prepared by reaction of a polyphenylene ether with an epoxychlorotriazine such as diglycidyl chlorocyanurate, n-butyl glycidyl chlorocyanurate or mesityl glycidyl chlorocyanurate.

Polyphenylene ether-polyamide copolymers from epoxytriazine-capped

Epoxytriazine-capped polyphenylene ethers are prepared by reaction of a polyphenylene ether with an epoxychlorotriazine such as diglycidyl chlorocyanurate, n-butyl glycidyl chlorocyanurate or mesityl glycidyl chlorocyanurate. The products undergo reaction with nucleophilic polymers such as polyamides and polyesters, to form copolymer-containing compositions which have excellent properties and which find utility as molding compositions and as compatibilizers for blends of similar polymers.

Epoxytriazine-capped polyphenylene ethers and method of preparation

Solvent-resistant resin blends with a wide variety of desirable impact and tensile properties are prepared from a polyphenylene ether having a low proportion of unneutralized amino nitrogen, a mixture of a poly(alkylene dicarboxylate) and a polyarylate, and, optionally, at least one elastomeric polyphenylene ether-compatible impact modifier.

Solvent-resistant, compatible blends of polyphenylene ethers and

Solvent-resistant resin blends with a wide variety of desirable impact and tensile properties are prepared from a polyphenylene ether having a low proportion of unneutralized amino nitrogen, a mixture of a poly(alkylene dicarboxylate) and a polyarylate, an aromatic polycarbonate as a compatibilizing agent, and, optionally, at least one elastomeric polyphenylene ether-compatible impact modifier.

Solvent-resistant, compatible blends of polyphenylene ethers, and

Epoxidized chlorotriazine compounds, useful to introduce one or more epoxide groups into nucleophile containing polymers, are prepared by reacting an epoxy alcohol with a cyanuric chloride or dichlorotriazine in the presence of base.
