1、成都理工大學(xué)畢業(yè)設(shè)計(jì)(論文)高吸水性樹脂的合成作者:范寶瑩班級(jí):200802020130專業(yè):化工與制藥指導(dǎo)老師:曾慶樂教授摘要高吸水樹脂又稱超強(qiáng)吸水劑,是由低分子物質(zhì)經(jīng)聚合反應(yīng)合成或由高分子化合物經(jīng)化學(xué)反應(yīng)制成,首次出現(xiàn)于20世紀(jì)60年代的是一種白色或微黃色、無(wú)毒無(wú)味的中性小顆粒。其具有分子量大、分子鏈長(zhǎng)、多分散性的特點(diǎn),是一種含有強(qiáng)的親水性基團(tuán)并具有一定交聯(lián)度的高分子。本文以丙烯酸(AA)和丙烯酰胺(AM)為單體,N,N′-亞甲基雙丙烯酰胺為交聯(lián)劑,以過硫酸鉀和亞硫酸氫鈉體系為引發(fā)劑,采用水溶液聚合法合成高吸
2、水樹脂聚丙烯酰胺-丙烯酸。樹脂在自來水中最大吸水量為105.42g/g。主要考察了丙烯酰胺單體濃度、引發(fā)劑對(duì)樹脂吸液性能的影響。關(guān)鍵字:高吸水樹脂,丙烯酸,丙烯酰胺,水溶液聚合;成都理工大學(xué)畢業(yè)設(shè)計(jì)(論文)ThesynthesisofsuperabsorbentpolymerName:BaoyingFanMajor:ChemicalandPharamaceuticsengineeringClass:200802020130Supervisor:ProfessorQingleZengAbstract:SuperAb
