摘要/Abstract

摘要： 通过细乳液聚合的方法制备了十一烯酸/甲基丙烯酸甲酯（UA/MMA）共聚乳液，研究了具有烯丙基结构的UA和引发剂用量对聚合过程及聚合物性能的影响。结果表明：UA参与了和MMA的共聚反应；随着UA用量的增加，乳液聚合速率下降，聚合物相对分子质量减小，玻璃化转变温度下降，聚合物热稳定性提高；随着引发剂用量增加，聚合物相对分子质量减小，转化率增大；粒径测试表明体积平均粒径在120 nm左右，且随着UA用量增加，乳液粒径稍有增大，但影响不显著；黏度测试表明共聚乳液黏度均处于10~15 mPa·s范围之内。

Abstract: Undecylenic acid/methyl methacrylate(UA/MMA) copolymer emulsion was prepared by miniemulsion polymerization. The effects of UA with allyl structure and initiator dosage on the polymerization process and polymer properties were studied. The results indicated that UA was involved in the copolymerization reaction with MMA. And with the increase of the amount of UA, the polymerization rate, molecular weight, and the glass transition temperature declined. But the thermal stability of the copolymer improved. As the amount of initiator increased, the molecular weight of polymer decreased and the conversion rate increased. Particle diameter test showed that the volume average particle diameter of enulsions was about 120 nm and increased slightly with the addition of UA. Viscosity test showed that the viscosity of copolymer emulsions was 10-15 mPa·s.

Key words: undecylenic acid, methyl methacrylate, miniemulsion, polymerization rate, relative molecular weight
