Polyimide thermoplasticity

In 1988 Heinze and Burton reported a facile synthesis of various a,p,P-trifluorostyrenes.15 These trifluorostyrene compounds were reported to be unstable to cyclodimerization at room temperature when stored neat, especially the compounds that were /lura-substituted with electron-donating substituents. They described the preparation of one compound, l,4-bis(trifluorovinyl)benzene with the observation that the material gelled when allowed to stand neat overnight. They offered the explanation that the gel was a polymer network connected with flnorinated cyclobutanes. Burton later went on to utilize this dimerization reaction for the cross-linking of polyimide thermoplastics.16... [Pg.42]

Synthesis of Siloxane-Polyimide Thermoplastics. In a typical siloxane-polyimide thermoplastic preparation, a 2-L, three-neck flask equipped with an overhead mechanical stirrer, Dean-Stark trap with condenser and nitrogen inlet, and a thermometer was charged with 106.41 g (0.230 mol) of DiSiAn, 119.71 g (0.230 mol) of BPADA, 49.74 g (0.460 mol) of mPD, 8.55 g (3 wt %) of 2-hydroxypyridine, and 635 mL of o-dichlorobenzene. The mixture was warmed to 100 °C for 1 h to dissolve the monomers and catalyst. Polyamic acids precipitated and redissolved when the mixture was heated to 150 °C for 1 h. The solution was then warmed to reflux, and 15 mL of water of reaction was removed by azeotropic distillation. The mixture was maintained at 180 °C for 16 h. The solution became noticeably more viscous. The polymer was isolated and purified as described previously to obtain 232 g (90%) of polymer with an IV of 0.54 dL/g. The isolated polymer was characterized spectroscopically. DSC indicated a Tg (glass transition temperature) of 196 °C. [Pg.167]

The most common thermosetting laminating resins are phenolics, melamines, epoxies, polyesters, silicones, and polyimides. Thermoplastic resins used in making laminates include polysulfone, polyphenylene sulfide, polyetheretherketone, polyamide-imide, polybutylene terephthalate, nylon 6, and polypropylene. [Pg.312]
