【摘要】 研究了三元丙烯酸酯 (甲基丙烯酸甲酯 MMA、丙烯酸丁酯 BA、丙烯酸 AA)共聚反应中的亲水单体丙烯酸 (AA)及引发剂过氧化苯甲酰 (BPO)用量对共聚物形成的无皂水溶胶的流变性、稳定性、表面张力的影响 .比较共聚反应条件对无皂水溶胶用于水性油墨性能的综合影响 ,确定了适用于交联型水性油墨的丙烯酸酯共聚物的合成条件为 φ(AA) =4%、BPO的质量浓度为 1 .8× 1 0 - 2 g/ m L,并通过 IR、NMR、GPC对共聚物进行了表征 .更多还原

【Abstract】 The effects of the amount of hydrophilic monomer acrylic acid(AA) and initiator benzoyl peroxide(BPO) in polymerization of acrylate terpolymer (consisted of methylmethacrylate(MMA), butyl acrylate(BA) and acrylic acid) on the properties of the acrylate terpolymer soap free hydrosol have been studied. The optimum contents of φ (AA) 4% and c (BPO) 1 8×10 -2 g/mL were selected. The terpolymer was identified by IR, 1H NMR and GPC. The hydrosol obtained had viscosity 20 5 mPa·s ( D 200 s -1 ), surface tension 31 mN/m and an improved stability, meeting the basic requirements of water based ink.更多还原
