GPC-analysis of polymer molecular weight distribution. Comparison between block copolymer and a random copolymer of similar composition and Mn. 聚合物分子量分布的GPC分析。嵌段共聚物與具有相似成分和分子量的無(wú)規(guī)架構(gòu)共聚物的比較。
Lower molecular weight and broader molecular weight distribution in thermoplastics favor lower orientation and reduced internal stress in moldings. 在熱塑性塑料中較小的分子量以及較寬泛的分子量分布促成方向性減少同時(shí)降低注塑件中的內(nèi)應(yīng)力。
The changes in the molecular weight and molecular weight distribution index of the resin during the semi-continuous polymerization were also researched. 本研究還考察了半連續(xù)聚合反應(yīng)進(jìn)程中苯丙樹脂分子量和分子量分布指數(shù)的變化規(guī)律。
