In small batch bulk PP/ nucleator system, The nucleator TMB-5 was used as the impact modification for different small batch bulk PP045 and PP075 in the second part of the project.

通过XRD分析表明，β成核剂TMB—5的加入使小本体PP的结晶度提高，并对β-PP有诱导生成作用，同时发现对小本体075具有较好的增韧效果，但使其强度有所下降。

Pimelic acid is a weak β nucleator ,the β crystal form which induced is not stable and transforms to αcrystal form during heating,so the DSC peaks widen.

庚二酸是低活性β晶型成核剂，生成的β晶型不稳定，易在加热时转变为α晶型，造成DSC熔融峰变宽。

In this paper POM is determined as base resin, the glassfiber and the carbon fiberare joinend to enhance, the toughener is acceded to toughen, the nucleator is entered tochange its crystallinity.
