摘要

采用聚甲基丙烯酸甲酯-b-聚甲基丙烯酸-r-丙烯酸嵌段无规共聚物作为稳定剂，进行了甲基丙烯酸甲酯（MMA）半间歇乳液聚合。通过调节pH值，在稳定剂含量极低（以单体为基础为0.01 wt%）的情况下，获得了粒径为30-200 nm的纳米乳液。

Emulsion Polymerisation Stabilised by Block-Random Copolymers: Ultra-Small Particles at Low Stabiliser Levels

Poly(methyl methacrylate)-b-poly(methyl methacrylate-r-acrylic acid) block-random copolymers were used as stabilisers in the semi-batch emulsion polymerisation of methyl methacrylate (MMA). By adjusting the pH, nano-latexes with particle sizes ~30-200 nm were obtained using a surprisingly low stabiliser content (~0.01 wt% based on monomer).
