【摘要】 本文报道了在汽—液相体系中,首次用TEA CO₂激光使甲基丙烯酸甲酯发生了聚合反应。激光诱导的聚合物的红外吸收图谱和标准的甲基丙烯酸甲酯聚合物的红外吸收图谱完全一致,并测定了聚合物分子量和热分解温度曲线。我们认为这是通过红外多光子吸收诱导的聚合反应。更多还原

【Abstract】 The melthyl methacrylate was submitted to TEA CO₂ laser radiation in the vapou-liquid phase and polymerization wasfirst time obserued。Infrared spectra of the polymer induced by infrared laser was all the same to standard polymer of the methyl methacrylate. The molecular weight and temperature curve of thermal decomposition of polymerwas measured. Amechamism of infr ared multiphoton absorption of molecular dissociation was suggested. Induced by infrared laser successful experiment on solids and insuccessful experiment on liquid have also been reported.更多还原
