Polyamidation of new diamine monomers containing bulky pendant groups based on imidazole ring and fabrication of polyamide/modified‐SiO2composite: Properties and applications
Abstract:Aiming to develop a novel series of high‐performance and organo‐soluble polyamides (PAs), two imidazole‐based diamines containing xanthene and voluminous pendant units were designed and polycondensed with common dicarboxylic acids. The polymers' excellent solubility in many organic solvents can be correlated to the introduction of flexible ether linkages and bulky pendant groups into the rigid structure of PAs. PAs possessed high thermal resistance (T10>420°C), high glass transition temperatures (Tg) (from 181… Show more
