甲基丙烯酸三丁基锡酯自由基溶液聚合反应动力学的研究
Study on the Kinetics of Radical Polymerization of Tributyltin Methacrylate in Solution
【摘要】 我们在苯溶液中,以偶氮二异丁腈为引发剂,在50°~75℃的温度范围内,进行了甲基丙烯酸三丁基锡酯(TBTM)的聚合动力学研究,得到了聚合反应速度方程式Rp=Kp[TBTM]1.5[A(?)BN]0.5,即对单体和引发剂的反应级数分别为1.5级和0.5级.并测定了聚合反应活化能为18.1kcal/mol,及影响聚合度的综合活化能为-12.3kcal/mol.
【Abstract】 The kinetics of polymerization of tributyltin methacrylate(TBTM)hasbeen studied in benzene solution at temperature range 50℃—75℃ in the prese-nce of azobisisobutyronitrile(AIBN),We have obtained the rate equation asfollowing:Rp=Kp[TBTM]1.5·[AIBN]0.5 The activation energy of polymeri-zation has been determined to be 18.1kcal/mol,The activation energy fordegree of polymerization is approximately-12.3kcal/mol.
