聚合方法和扩链剂对乳酸聚合物相对分子质量的影响
Influence of Polymerization Methods and Chain-Extension Agent on Relative Molecular Weight of Polylactide
摘要
Abstract
The influence of melt polycondensation a nd solvent refluxing methods of lactide polymerization and chain-extension agent s on relative molecular weight of polyla ctide was studied．It was found that the r elative molecular weight of the products from solvent refluxing method was 2～3 t imes higher than that of the products fr om melt polycondensation method．However， the relative molecular weight of the pro ducts for polylactide was increased more than ten times on using chain-extension agents．关键词
