Superhydrophobic Surfaces from Various Polypropylenes

Langmuir, 2008
Superhydrophobic surfaces were prepared from solutions of isotactic polypropylenes of various molecular weights using soft chemistry. Varying the conditions of the experiments (polymer concentration and initial amount of the coated solution) allowed us ...

Microstructure of polypropylene

Progress in Polymer Science, 2001
Abstract For over thirty years after the discovery of stereoselective olefin polymerization in 1954, the word ‘polypropylene’ has meant, both scientifically and commercially, little else than the predominantly isotactic polymer achievable with the classical heterogeneous Ziegler–Natta catalysts.

Photodegradation of polypropylene and polypropylene containing pyrene

Polymer Photochemistry, 1983
Abstract The photodegradation of polypropylene (PP) and polypropylene containing pyrene (Py) as an additive has been studied by electron spin resonance (ESR), infra-red (IR) and ultra-violet (UV) absorption measurements. When PP film is irradiated with UV light at −196°C, alkyl-type radicals are produced.

Polypropylene nanocomposite with polypropylene-grafted graphene

Macromolecular Research, 2016
A method for grafting polypropylene (PP) onto graphene oxide (GO) surfaces was successfully established by functionalizing GO with (3-aminopropyl)triethoxysilane (NH2-t-GO) and grafting maleic-anhydride-grafted PP (MAPP) on NH2-t-GO (MAPP-g-GO). The PP/GO nanocomposites were prepared by compounding MAPP-g-GO with virgin PP.

Crystallization behaviors of polypropylene and functional polypropylene

Journal of Applied Polymer Science, 2003
AbstractThe crystallization behaviors of polypropylene (PP) homopolymer and its blends with 0–15% functional polypropylene (FPP), the backbones of which were grafted with guanidine and diamide polymer chains, were investigated with differential scanning calorimetry and wide‐angle X‐ray scattering. The crystallization kinetics were studied with spectral

Polypropylene

Ophthalmology, 1981
Polypropylene is a polymer widely used in lens implantation, both as a loop material and as an intracameral suture. The chemistry and qualities of this material are discussed. Predicated on its usage in other types of surgery, it appears to be resistant to degradation.
