摘要
本文根据溶液缩聚基本原理及反应过程的基本事实,用随机过程方法,得到缩聚产物分子量分布函数,并对分子量及其分布的控制作了讨论。
According to the basic principles of solution condenstion polymerization and the basic facts of such process,by usinq on random process method,the mol- ecular weight disribution fuction of the solution condensation polymers has been derived to obtain F(t,M)=1/(2(πbt)^(1/2))exp(-(M-2at)~2/(4bt))dM The average molecular weight is. m(t)=2at and the variance is: (t)=2bt Furthemore,the control of molecular weight and its distribution has also been discussed.
