The melting and recrystallization behaviour of poly(vinylcyclohexane)-b-poly(ethylene)-b-poly(vinylcyclohexane)(PVCH-PE-PVCH) triblock copolymer in supercritical carbon dioxide(CO2) was investigated by(using...
The crystallization of poly(vinylcyclohexane)-b-poly(ethylene)-b-poly(vinylcyclohexane)(PVCH-PE-PVCH) triblock copolymer/chloroform solution was investigated. The solvent of the solution system was evaporated at vario...
The hexamethylphosphoramide(HMPA)-containing wastewater was treated by solvent extraction. The ef-fects of a series of extractants, the amount of extractant and the concentration of the HMPA in aqueous solution were i...
