本文报道了丙烯酸酯和甲基丙烯酸酯与非极性1-烯烃在Bronsted酸络合剂存在下的首次共聚合反应。均相和非均相布朗斯台德酸的加入导致单体转化率和I-烯烃掺入增加。此外，异质布朗斯台德。酸可以再循环而不损失活性。刘易斯酸或布朗斯台德酸与丙烯酸酯/甲基丙烯酸酯单体的酯基结合的能力与其促进共聚反应的能力之间存在直接的相关性。对于刘易斯酸，在金属中心的电荷/尺寸比与它们促进共聚的能力之间也存在直接的相关性。(C)2008 Wiley Periodicals，Inc.
The first copolymerization of acrylate and methacrylate with nonpolar 1-alkenes in the presence of Bronsted acids as complexation agents has been reported. The addition of both homogeneous and heterogeneous Bronsted acids resulted in increased monomer conversion and I-alkene incorporation. Further, the heterogeneous Bronsted. acids can be recycled without loss of activity. A direct correlation exists between the ability of the Lewis or Bronsted acid to bind to the ester group of the acrylate/methacrylate monomer and its ability to promote the copolymerization reaction. For Lewis acids, there is also a direct correlation between the charge/size ratio at the metal center and their ability to promote copolymerizations. (C) 2008 Wiley Periodicals, Inc.
