摘要
分别以两亲聚合物 P(C9- AA)和 P(DCPD- St-α- St- AA)作乳化剂 ,研究了制备大颗粒 (约 1μm)及具有一定稳定性的苯丙乳液的方法 ,讨论了乳化剂 ,温度及引发剂用量对乳液性能的影响。结果表明 ,以P(C9- AA)作乳化剂时 ,引发剂用量为单体质量的 1.2 % ,90℃时可以合成性能良好的苯丙乳液 ;以P(DCPD- St- α- St- AA)作乳化剂时 ,引发剂用量为单体质量的 1.2 % 。
The polymer of P(C 9-AA) and P(DCPD-St-α-St-AA) were synthesized and used as emulsifiers to prepare high solid content, large particles and stable poly (styrene /acrylate /methyl methacrylate /acrylic acid) emulsion. The effects of emulsifiers, temperature and initiator concentration on the properties of emulsion were discussed, respectively. The best conditions of polymerization are 90 ℃, ammonium persulfate 1.2 mass% (to monomer), 40% solid content when P(C 9-AA) is used as emulsifier, and 80 ℃～90 ℃, ammonium persulfate 1.2 mass% (to monomer), 50% solid content when P(DCPD-St-α-St-AA) is used as emulsifier.
