Several fluorine-containing polyester laminating resins were prepared. Of the laminates prepared, the fluorinated glycol polyester laminates exhibited superior high temperature properties compared with the hydrocarbon glycol polyester laminates with one exception. Fluorinated and hydrocarbon laminates prepared with maleimide-triallyl cyanurate mixtures were compared by examining their flexural strengths at 260 deg C. A hexafluoropentanediol polyester cross linked Adth maleimide yielded a laminate that retained 95% of its initial 260 deg C flexural strength (39,900 psi) after aging 100 hr at 260 deg C. The flexural strengths of hydrocarbon laminates at 260 deg C after aging 100 hr exhibited low initial strengths (17,000 to 25,000 psi), became weaker after aging 8 to 26 hr (10,000 to 12,000 psi), and then became progressively stronger. The flexural strengths of laminates prepared from mixtures of triallyl cyanurate and maleimide were approximately the same at 260 deg C after aging 100 hr. Glass cloth laminates were prepared from perfluoroglutarimidine. These laminates exhibited low flexural strengths, but preliminary tests at 400 to 700 deg F indicated low weight losses and good retention of strength.
