A STUDY ON THE LAMELLAR MORPHOLOGY OF ISOTACTIC POLYPROPYLENE

CHEN Shouxi, JIN Yongze(Institute of Chemistry, Academta Sinica, Beijing, Post code, 100080)  
A study is presented concerning the three different structural levels of isotactic polypropylene (iPP). Involved wkhin, is the coordinated application of optical and electron microscopy on both α-form and β-form iPP, crystallized from melt. For TEM in particular, the RuO4 staning technique has been used to reveal the lamellar morphology in both spherulites of iPP. The investigation itself has centred on the different spherulite types, as identified optically, which were correlated with the details of their particular lamellar morphology. The lamellar morphology of both iPP crystallized from melt drawing has also been studied.
