以甲基丙烯酸为原料，通过树枝状溴化物与甲基丙烯酸反应，合成了3种树枝状片段的甲基丙烯酸烷基酯单体，其中2种为Frechet型，1种为第一代3，5-二苯氧基苄基的新型甲基丙烯酸烷基酯单体，并在自由基引发剂作用下进行均聚反应。第一代侧基聚合物的聚合度Pn为17-24，明显高于第二代侧基聚合物（Pn为6-7）
Alkyl methacrylate monomers with three kinds of dendritic fragments as alkyl groups, two kinds of Frechet-type and a new type with 3,5-diphenoxybenzyl as first generation were prepared by reaction of the corresponding dendritic bromides with methacrylic acid in good yield and were homopolymerized with a radical initiator. Polymers with side groups in first generation had a degree of polymerization P n of 17-24, markedly higher than those with side groups in second generation (P n ≃ 6-7)
