【摘要】 <正> 自从激光问世以来,以其高光亮度、单色性、定向性和超短脉冲性使人们在用激光进行同位素分离、浓缩铀等方面取得了长足的进步,利用超短脉冲激光进行反应动力学研究已开始起步,但是,鉴于能量因分子碰撞而损失,许多研究都是在低气压条件下进行的,以单体直接进行激光液相聚合的例子不多,目前还未见以激光进行阴离子型的聚合反应。我们利用激光能定向离解某一键的特点,以连续输出单模运转的CO₂激光,在未聚焦的情况下,对甲更多还原

【Abstract】 In this paper,the PMMA is synthesized with continuous-wave laser,and its structural tacticity mechanism of polymerization has been studied by IR NMR and HPLC.We find that PMMA can be synthesized on irradiation with CO2 Laser,and the reaction of MMA monomer irradiated at 10.6μ induced anionic polymerization.更多还原
