  • High strength thermoset copolymers incorporating modified bisoxazoline monomers.
    Patent number: 5644006
    Abstract: The present invention provides novel thermoset copolymers, and methods for preparing same, having both the strength and the thermo-oxidative stability required for high performance, high temperature applications. The copolymers comprise (a) a thermoplastic resin having unreacted phenolic OH groups, and (b) bis-oxazoline monomers which have been modified to have at least one substituent on the oxazoline ring selected from the group consisting of a methyl group, a group having at least a substituent capable of undergoing addition polymerization, and a cyclic group capable of undergoing ring opening polymerization.

  • Toughened thermosetting resin composites and process
    Patent number: 5403655
    Abstract: Toughened thermosetting resins are disclosed comprising a thermosetting resin having a Tg of at least 150.degree. C., preferably 180.degree. C., and having dispersed substantially uniformly therethrough microspheres of a thermoplastic resin having a Tg of at least 150.degree. C., preferably 180.degree. C. It is preferred to use thermoplastic resins with functional groups on the surface thereof capable of bonding to an available group on the thermosetting resin. High performance structural composites made from such toughened resins are disclosed as well as the process of making such composites.
