The polymer with a viscosityaverage molecular weight beyond 200 000 was fairly reproducible by optimizing the polymerization conditions.
优化聚合条件可以获得粘均分子量大于200 000的聚丙交酯材料,聚合结果具有良好的重复性。

The viscosityaverage molecular weighs of several different CPPs were determined by dilute solution viscometry and the intrinsic viscosity was related to the viscosity of industry concentration.
The degree of deacetylation of chitosan prepared by the optimum condition is 88.53%, the viscosityaverage molecular mass is 9048. The experimental result mainly accorded the prospective desire.
