| Abstract: | With the aid of computers to increase the capacity of analysis and data processing,scaling the molecular weight of polymers simultaneously in the process of reaction has been realized.In the experiment of scaling the molecular weight of PVA,Ubbelohde vis- cosity method was put forward for measuring the inherent viscosity.By using computers to deal with the data and fit the function,the molecular weight of PVA is calculated.This way the accuracy is increased and the research period is curtailed. |
