“…Thus, epoxy-anhydride polymers modified by oligofluorosiloxanes exhibit good comprehensive properties, including improved contact angle, surface energy and water absorption, that make them suitable for a potential application in LED packaging [20]. Embedding of polyfluoroalkylcontaining oxiranes enhances hydrophobicity and heat resistance of the resulting epoxy polymers [21,22].…”

Technique of the preparation of the anhydrideterminated polyfluoroaromatic oligoimides from tetrafluorophenylene or hexafluoronaphthylene diamines and oxydiphthalic anhydride was elaborated. These compounds were used as modifiers and cohardeners for an epoxyanhydride formulation composed of resin DGEBA and isomethyltetrahydrophthalic anhydride. Curing parameters of the modified epoxy-imide formulations were investigated using DSC, DMA, and FTIR spectroscopy. The modified epoxy polymers containing the polyfluoroaromatic imide fragments have improved thermomechanical and thermooxidative characteristics and hydrophobicity. The modifiers exert a positive effect on the elastic modulus, flexural strength, and dielectric permittivity of the epoxy-anhydride polymers when their amount reaches 20-30 pbw. The anhydride-terminated polyfluoroaromatic oligoimides appears to be promising for the preparation of epoxy polymers with improved performance.

“…The following works exemplify this approach [16][17][18][19][20][21][22]. For instance, addition of amino-and carboxyl-terminated butadiene-acrylonitrile rubbers to nanofilled epoxy composites provides fivefold increase of the fracture energy [16].…”
