ACRYLONITRILE/POLY(ETHYLENEGLYCOL)METHACRYLATE COPOLYMER MANUFACTURED BY BULK COPOLYMERIZATION, PREPARING METHOD THEREOF AND MEMBRANE FOR WATER-TREATMENT MANUFACTURED BY THAT

摘要

PURPOSE: A acrylo night / poly (ethylene glycol) methacrylate copolymer, and a manufacturing method thereof and a membrane for water treatment using the same are provided to have suitable absolute viscosity for manufacturing the membrane for the water treatment, and have excellent mechanical property including the impact tolerance of the membrane for the water treatment etc, and to have excellent membraned contamination resistivity especially. CONSTITUTION: The manufacturing method of the acrylo night / poly (ethylene glycol) methacrylate copolymer includes the steps of: performing the bulk polymerization in 40 ~ 60°C after stirring the mixture of acrylonitrile monomer, the poly (ethylene glycol) methacrylate monomer and polymerization initiator under the anoxic atmosphere; stabilizing the polymeric composition by precipitating in the hexane of -30 ~ 0°C for 10 ~ 15 hours; after smashing after melting the stabilized polymeric composition in the benzene, re-stabilizing the polymeric composition ;by precipitating the smashed polymeric composition in the hexane of -30 ~ 0°C for 10 ~ 15 hours; and manufacturing the polymer after repeating the stabilizing and re-stabilizing steps for 2~5 times.
