• 中文摘要： 本文利用視反應常數模式推衍出以半回批法控制定組成共聚合反應之嚴密解(Exact Solution)。此半回批法係以兩階段式分別以單體進料及起始劑進料控制共聚合物組成,聚合速率及分子量大小與分布。並以苯乙烯與丙烯之溶液共聚合反應為例加以說明之。其苯乙烯單體反應組成為0.1至0.5莫耳百分率。
• 英文摘要： A two step process is suggested for the semibatch feed policy for constant composition copolymerization. The aims of the policy suggested are to control composition, rate, and qualities of copolymerization. In the reactor analysis, the apparent rate constant model is adopted for the rate expressions of copolymerization. The feed rates of the more active monomer and the initiator for compensating composition, and for adjusting rate and molecular weights as well as the course of polymerization and qualities of copolymerization are worked out analytically. Solution copolymerizations of styrene and acrylonitrile are chosen as the system for illustration. The numerical results for conducting the constant composition copolymerizations of 0.1 to 0.5 mole fraction styrene are given.
