| Abstract: | According to the pilot mode, the n-Buli /THF was used as initiating system,the styrene and butadiene were used as feed stocks ,the commerial study was finished, and a kind of block structured copolymer was acquired, namely, the styrene butadiene transparent impact resin.The solvent was removed from the copolymer by using a twin-screw evaporation extruder so that the evaporation, transportation, plasticizing, compress and extruding were completed in one extruder.The effects of the reaction temperature, minim impurities and extruding parameters on the reaction and product quality of polymerization were examined. |
