Mar 19, 2019 · The polymorphism of crystals of polypropylene is presented and discussed. The general aspects of crystal nucleation and growth are recalled and typical structures crystallizing in polypropylene are characterized: single crystals, spherulites, shish-kebabs.
Dec 4, 2023 · ABSTRACT: The present study is aimed at investigating the molecular structure, crystallinity, and morphology of polyethylene (PE) and polypropylene (PP) blends by using Raman mapping, scanning...
Introducing the permanganate chemical etching procedure, a new spherulite investigation method of scanning electron microscope (SEM) is developed for the observation of isotactic polypropylene (iPP).
Feb 1, 2007 · Environmental scanning electron microscopy (ESEM) provides new tools to examine the dynamic behaviour of various materials under different conditions. The dynamic experiments of water wetting, oil sorption and loading deformation of polypropylene (PP) nonwovens in the ESEM were studied in this paper.
Jul 28, 2025 · Polypropylene is a thermoplastic resin that is a product of the polymerization of propylene and ethylene gases. Though it may be created in a variety of forms, only isostatic polypropylene, which was discovered in 1954, is widely utilized for commercial purposes.
Nov 13, 2015 · Polypropylene is a thermoplastic resin that is a product of the polymerization of propylene and ethylene gases. Though it may be created in a variety of forms, only isostatic polypropylene, which was discovered in 1954, is widely utilized for commercial purposes.
Nov 15, 2023 · Scanning electron microscopy (SEM) investi-gations of polypropylene fibres coloured with a quinacridone pigment were per-formed. The fibres extruded at different velocities were investigated.
