Effect of different inorganic filler over isothermal and non-isothermal crystallization of polypropylene homopolymer
(Springer, 2012-02)
In this study, the effect of several inorganic fillers: silicon oxide (SiO2), nanoclay (C20A), alumina (Al2O 3), and calcium carbonate (CaCO3) on the crystallization behavior of polypropylene were analyzed for composites ...
Influência de diferentes aditivos nucleantes na morfologia e nas propriedades do polipropileno moldado por injeção
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2018-10-25)
Samples of a polypropylene (PP) homopolymer were nucleated with three different nucleating agents: 1,3:2,4-bis (3,4-dimethylobenzylideno) sorbitol (DMDBS), bis(4-propylbenzylidene) propilsorbitol (propilsorbitol), and ...
Estimation of the Molecular Weight Distribution of Linear Homopolymer Blends from Linear Viscoelasticity for Bimodal and High Polydisperse Samples
(Planta Piloto de Ingeniería Química, 2003-11)
This work is concerned with the approximate solution of the problem generated by the integral of first kind relating the shear relaxation modulus of entangled, linear and flexible homopolymer blends and the molecular weight ...
Assessment of impact fracture toughness of PP-elastomeric polyolefin blends
(Taylor & Francis, 2002-01)
The present investigation is concerned with evaluation of the impact fracture toughness of novel blends based on commercial polypropylene homopolymer (PPH) and elastomeric polyolefin (POEs). At room temperature and high ...
Syndiotactic Polypropylene and its Copolymers with Alpha-Olefins. Effects of Composition and Length of Comonomer
(2005)
A set of copolymers of propene and alpha olefins (1-hexene, 1-octene and 1-octadecene) and the corresponding homopolymer (sPP) have been synthesized using a syndiotactic metallocene catalyst. The effect of either the ...

Structural and thermal properties of polypropylene mesh used in treatment of stress urinary incontinence
(Wroclaw Univ Technology, 2009-01-01)
Besides material biocompatibility, it is possible to infer that both vaginal and urethral erosion rates associated with sub-urethral synthetic slings may be related to the mechanical properties of the meshes and also to ...
