Preparation and Characterization of Poly(aryl ether sulfone)Copolymers Containing Imidazolyl Group
摘要
Abstract
A series of different content of benzimidazolone and 5,6-dimethyl-2-benzimidazolone poly(aryl ether sulfone) copolymers with side groups were synthesized by copolymerization on the basis of poly(aryl ether sulfone) with cardo group(PES-C).The structures and properties of the copolymers were characterized by nuclear magnetic resonance spectroscopy(NMR), Fourier transform infrared spectrometer(FTIR), thermal gravimetric analyzer(TGA) and so on.The resulsts show that poly(aryl ether sulfone) copolymers are amorphous.The copolymers exhibit good heat resistance, and present a single glass transition temperature(Tg>271 ℃), when the mole fraction of benzimidazolone and 5,6-dimethyl-2-benzimidazolone increases, the copolymer glass transition temperature rises, ranging from 270 ℃ to 318 ℃ and 314 ℃, respectively.At the same time, the copolymers have good thermal stability.These copolymers have good solubility in N,N-dimethyl formamide(DMF), N,N-dimethylacetamide(DMAc), dimethyl sulfoxide(DMSO), N-methyl pyrrolidone(NMP) which are the commonly polar aprotic solvents, and trichloromethane(CHCl3).Based on good solution processability and film-forming properties, the toughness thin film can be prepared by solution preparation.关键词
