| 摘 要： | 通过采用聚乙烯醇（PVA）、丙烯酸丁酯（BA）、甲基丙烯酰氧乙基三甲基氯化铵（MTA）为原料，采用无乳化剂乳液聚合法，制备出了一种阳离子共聚物乳液。测定了此乳液的转化率并考察了稳定性；同时发现当单体配比m（BA）：m（MTA）85：15时，引发剂（NH4）2S2O8为单体量的0.3％制得共聚物，其用量为1．2％（对绝干浆）时。可使纸张的环压指数提高29．86％，抗张指教提高30．92％。

| Abstract: | The paper discloses the quaternary copolymerization of the PVA- BA-MTA to increase the dry strength especially the circular pressure exponential and tensile strength for papermaking as the new-type dry strength agent. The cationic emulsion copolymer can be prepared in the ratio of m (BA):m (MTA) equal to 85:15 and with the (NH4)2S2O8 as initiator. The dry strength agent have showed the obvious effect to increase the circular pressure exponential of paper more than 29.86% and the tensile strength about 30.92%. |
