Patent number: 5049619Abstract: Two-component polymeric compositions having two interconnected solid phases, and exhibiting spinodal decomposition morphology at the domain boundaries are shown, as are methods for forming the same. The compositions are prepared from two different polymers one of which possesses ductility in that it shows substantial yield behavior under tensile stressing, the other being brittle, exhibiting no such behavior; thermoplastic polymers, in conjunction with thermotropic liquid crystalline materials, exemplify such systems. The desired morphology is created by preparing the two component compositions in a single solid phase below the lower critical solution temperature of the compositions, and thereafter heating the compositions above such temperature to form a two-phase system.Type: GrantFiled: April 14, 1989Date of Patent: September 17, 1991Assignee: Edison Polymer Innovation CorporationInventor: Thein Kyu

Patent number: 5041504Abstract: 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.Type: GrantFiled: June 29, 1989Date of Patent: August 20, 1991Assignee: General Electric CompanyInventors: Sterling B.
