Abstract : A rationale is presented for the development of room temperature curing polymers with the potential for 350 F performance. Such a polymer system must have a glass transition temperature (Tg) near room temperature, yet be highly crosslinked for good modulus retention at elevated temperatures. In order to test the hypothesis, epoxy resins have been prepared and used in room temperature cure studies directed to the development of polymer systems which will exhibit elevated temperature (350 F) performance.
