Semibatch Process As an example, acrylamide (0.8 g, 11.26 mmol), 20wt % of the total 0.2 g of the polyDMAEMA-DMSmacromonomer (Table 1, entry 10;molecular weight after quaternization ＝27,400; 0.040 g,0.00146 mmol of polyDMAEMA-DMS chains),and 30 wt % of the total 10 mg of AIBA (3 mg) in16.8 mL of deionized water (5 wt % of the totalsolution consisted of monomers) were initially charged to a reactor equipped with a magnetic stirrer and were purged with high-purity nitrogen for 30 min. PolyDMAEMA-DMS macromonomer (160 mg) and 7 mg of AIBA in 3.2 mL of deionized water were fed into the reactor at a constant feeding rate controlled by a pump during a 2-h period. A sample (0.5 mL) was taken each time at preset time intervals with a degassed syringe and was precipitated in methanol. The conversion was calculated from the ratio of the weight of the dried polymer collected over that of the total comonomers initially charged to the sample (5 wt % of the solution). 主要是药品的投放比例没有搞清楚，重点是前几句话的翻译，后面几句不用， |

我拿不准的就用英文代替了

Semibatch 程序： 举个例子：丙烯酰胺(0.8 g, 11.26 mmol), 总量是０.２g的the polyDMAEMA-DMSmacromonomer 中占质量百分含量的20 %，（表一，条目１０，季铵化作用后的分子量为27,400；0.040 g,0.00146 mmol of polyDMAEMA-DMS chains),总量１０mg中含有质量百分含量为３０％的氨基异丁酸（３mg）加入16.8 mL 去离子水（质量百分含量为5 %the totalsolution 单体组成）磁力搅拌，反映开始通入纯氮３０分钟．．．．．． [ Last edited by superli on 2007-7-5 at 12:43 ] |
