拜托啦,我要的是人工翻译,而不是在线直接复制粘贴的啊。
这个是我毕业论文的摘要。
我的英语不好,哪位高手能帮帮我啊。谢谢!!我再追加100分
Based on the theory and the polymerization of new technology, new technologies, especially at home and abroad silicone modified acrylic emulsion of a comprehensive summary of progress on the basis of a methyl methacrylate (MMA) , Butyl acrylate (BA), 4-4 4 vinyl Central siloxane (ViD4) as raw materials, use of vinyl 4-4 4 siloxane Central acrylate chemical modification of the Semi-continuous use of the principle of pre-core-shell emulsion polymerization method used ammonium sulfate (APS) as the initiator system had acrylic - silicone emulsion. Emulsion on the Synthesis of emulsifier in the best dosage and the polymerization of determining the appropriate choice of temperature, the amount of emulsifier the best: 4%, polymerization temperature :75-80 ℃. Also explore the surface tension, emulsifier, the reaction temperature on the emulsion performance of the series, and the infrared spectra of the polymer. It was found that the amount of emulsifier and the different temperature of the
