长链支化聚丙烯(LCBPP)相比线型聚丙烯(PP)有更高的熔体强度,更好的热稳定性,加工温度范围更宽,具有更广泛的应用场景. 本文首先总结了LCBPP的制备方法(外加大分子单体法、直接共聚法、射线辐照法、交联制备法和熔融反应加工法),介绍了不同制备方法的主要优缺点;其次,简述了用于测试LCBPP结构与性能的表征方法. 最后,对LCBPP未来的研究方向进行了展望.
Long-chain branched polypropylene (LCBPP) exhibits superior melt strength
enhanced thermal stability
and a broader processing temperature window than conventional linear polypropylene (PP)
improving its suitability for diverse industrial applications. This review focuses on recent advancements in LCBPP preparation methodologies
including macromonomer incorporation
direct copolymerization
radiation-induced branching
cross-linking techniques
and reactive melt processing
with a systematic comparison of their advantages and limitations. Characterization protocols for differentiating LCBPP from linear PP architectures were also addressed. This review outlines future research priorities
emphasizing that while China's LCBPP research is gaining momentum
substantial R&D investment remains imperative to develop high-value-added materials and strengthen China's global market competitiveness.
