摘要
本文研究了烷氧甲酰基双环［２，２，１］庚基丙烯酸酯（烷氧基为甲氧基、乙氧基、丁氧基）的自由基聚合动力学，得到了相应的聚合反应动力学方程和表现活化能。测定了聚合物的玻璃化转变温度。
The titld acrylates have been synthesized via Diels-Alder addition reac-tion using cyclopentadiene and acrylic esters as starting materia1s.The polymeriza-tion kinetics of these monomers have been studied and the kinetic equations were Obtained as follows:R_p=K[BPO]￣(0.50)[MCHA]￣(1.04),R_p=K[BPO]￣(0.49)[ECHA]￣(0.99),R_p=K[BPO]￣(0.51)[BCHA]￣(1.0),and the overall activation energy were determined to be E_a=87. 2kJ/mol ,95. 7kJ/mol,102.5kJ/mol for MCHA,ECHA,BCHA,respectively.T_g of,PMCHA,PBCHA were also determined.To be compared with PMA,PEA,PBA,it was found that T_g of PMCHA and PBCHA were increased greatly than that Of PMA,PEA PBA,due to their bulky bicycloaliphatic side group.
