摘要

利用示差扫描量热分析仪（DSC）、高温凝胶渗透色谱仪（HT-GPC）、温度梯度相互作用色谱（TGIC）、交叉分级色谱（CFC）及核磁共振波谱（

C-NMR）系统研究了多种具有不同熔融指数、密度和共聚单体类型的商品化聚烯烃弹性体（POE）的链结构，形成了全面表征POE相对分子质量及其分布、短链支化度分布、短链支化链间分布、共聚单体序列分布等链结构的立体化方法，从而便于构建不同POE产品的结构性能构效关系。本工作可为POE的分子结构设计和性能调控提供研究方法参考。

Abstract

Systematic investigations were performed on the chain structure of several commercial polyolefin elastomers (POE) with different melt indices and densities by employing differential scanning calorimetry (DSC)

high-temperature gel permeation chromatography (HT-GPC)

temperature gradient interaction chromatography (TGIC)

cross fractionation chromatography (CFC)

and carbon nuclear magnetic resonance spectroscopy (

C-NMR). It provided a useful method to comprehensively characterize the molecular weight

molecular weight distribution

degree

and intra- and inter-chain distribution of short chain branching

as well as the sequence distribution of different POE samples

aiming to determine the structure-property correlation. The present work would be helpful for the design of molecular structures and control of physical-mechanical properties.
