Ala~a~tet--Syndiotactic polypropylene has been studied by investigation of NMR line-width and second moment at various temperatures. Results for the syndiotactic material are compared with those for atactic and isotactic polypropylene. Line width and second moment of the absorption line were evaluat

The directional solidification of polypropylene (PP) films results in an oriented semicrystalline microstructure and may offer a method to improve the properties of a product. The directional solidification of isotactic PP samples blended with 0% to 50% atactic PP, by mass, was therefore studied. Th

The research in this article explores the response of semicrystalline isotactic polypropylene to gamma radiation in air, and relates the morphological changes of the polymer to corresponding changes in mechanical properties. The effect of the initial morphology of the polymer on its response to irra

Al~met--Thermal behaviour of gamma irradiated free radical and isotactic polymethyl methacrylate has been studied at 256 °. It is shown that radiolytic chain scissions do not produce unsaturated chain ends identical to those formed by disproportionation during free radical polymerization. Furthermo
