Abstract: Blended polymer compositions are described which comprise:(A) at least about 5% by weight of at least one polyphenylene ether;(B) up to about 95% by weight of at least one block polyetheramide; and(C) from 0 to about 3% by weight based upon the total weight of components (A), (B) and any other polymers present in the composition of at least one polyepoxide;with the proviso that when said block polyetheramide has a flex modulus greater than about 75 MPa., said composition contains at least about 0.5% by weight based upon the total weight of components (A), (B) and any other polymers present in the composition of said polyepoxide.The blends give non-delaminating molded parts with good mechanical properties. The blends can be formed from a high-nitrogen polyphenylene ether and a block polyetheramide without the need for using vacuum-vented polyphenylene ether extrudate and without the need for adding a compatibilizer.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
