Aluminum trichloride (AlCl3) catalyzed copolymerization of polar monomers, including both methyl methacrylate (MMA) and methyl acrylate (MA), with nonpolar 1-octene is investigated. The copolymerization of MMA and 1-octene produces copolymers with acceptable productivity in the present of AlCl3, but no alternating copolymer can be obtained even in a 1-octene rich condition (n(1-octene)/n(MMA) = 6.14/1). However, AlCl3-catalyzed copolymerization of MA and 1-octene unveils that MA is more feasible than MMA to copolymerize with 1-octene for the formation of alternating copolymer. An alternating copolymer of MA and 1-octene can be obtained even at MA-rich conditions (n(1-octene)/n(MA) = 0.58/1). Meanwhile, temperature shows a significant impact on the copolymerization behaviors. Performing AlCl3-catalyzed copolymerization of MA and 1-octene at lower temperature leads to an increase in the molecular weight and the incorporation of MA into the backbone of the copolymer, probably due to low temperature-enhanced complexation between AlCl3 and the ester functionality.

深入了解甲基丙烯酸甲酯和1-辛烯与三氯化铝的共聚合

研究了三氯化铝(AlCl 3)催化的极性单体(包括甲基丙烯酸甲酯(MMA)和丙烯酸甲酯(MA))与非极性1-辛烯的共聚反应。MMA和1-辛烯的共聚可在AlCl 3存在下生产出具有可接受生产率的共聚物,但即使在富含1-辛烯的条件下(n(1-辛烯)/ n(MMA)= 6.14 / 1)。然而,AlCl 3催化的MA和1-辛烯的共聚揭示了MA比MMA与1-辛烯共聚形成交替共聚物更可行。即使在富MA条件下(n(1-辛烯)/n(MA)= 0.58 / 1)。同时,温度显示出对共聚行为的显着影响。在较低温度下进行AlCl 3催化的MA和1-辛烯的共聚反应可能会导致分子量增加以及MA掺入共聚物的主链中,这可能是由于AlCl 3和酯官能团之间的低温络合作用所致。。
