Thermal, Mechanical, and Dielectric Characterization of p-tert-Butylcalix[8]arene Glycidyl Ether/Benzoxazine Copolymer
After thermally curing p-tert-butylcalix[8]arene glycidyl ether with benzoxazine, the thermal, mechanical, and dielectric properties of the copolymer products were evaluated. Incorporation of p-tert-butylcalix[8]arene glycidyl ether into the benzoxazine resin greatly increased both the glass transition and the thermal decomposition temperatures. Conversely, the fracture toughness of the polymer network decreased as the epoxide content increased, and the highest flexural strength was found in the sample with an epoxide/oxazine molar ratio of 10/90.
