如果忽略主链和终止反应的影响，在多官能转移剂存在下的自由基聚合的理论方法可以以简单的方式导出。在此条件下，当链转移常数C = 1时，通过初等概率论和母函数推导出了数均聚合度、重均聚合度、分散指数和重量分布函数的解析表达式。数值例子报告分布参数，官能度和单体转化率之间的关系。
The theoretical approach to free-radical polymerization in the presence of polyfunctional transfer agents can be derived in a simple way if the effects of primary chains and termination reactions are neglected. Under these conditions, and for values of the chain transfer constant C = 1, the analytical expressions for the number- and weight-average degree of polymerization, dispersion index and weight distribution function were derived through the elementary probability theory and generating functions. Numerical examples are reported on the relationship between distribution parameters, functionality and monomer conversion.
