Morphological raman analysis of short chain branched ethylene and propylene metallocenic copolymers
(Elsevier, 2018-05)
Spectroscopic features in the Raman spectra of semicrystalline polyolefins that characterize different phase morphologies are reported. With growing incorporation of different 1-olefins, changes in the spectra due to ...
Comparative Effect of Metallocene and Ziegler-Natta Polypropylene on the Exfoliation of Montmorillonite and Hectorite Clays to Obtain of Nanocomposites
(2007)
The present study was carried out on the effect of molecular weight and polydispersity of polypropylene (PP) obtained via Ziegler‐Natta or metallocene catalysis on the formation of nanocomposites with montmorillonite and ...
Metallocenic polyolefin composites with siloxane polymer additives
(Pergamon-Elsevier Science Ltd, 2018-10)
Blends and composites were obtained by mixing commercial metallocenic linear low density polyethylene (LLDPE) and isotactic polypropylene, with different molecular weight polydimethylsiloxanes (PDMS), including a vinyl ...
Microporous membranes prepared via thermally induced phase separation from metallocenic syndiotactic polypropylenes
(2009)
Microporous membranes were prepared by thermally induced phase separation (TIPS) using different tailor-made syndiotactic polypropylenes (sPP) synthesized by metallocene catalysts. The phase diagrams of sPP samples in ...

A study of the effect of styrene concentration on the molecular weight of polypropylene produced using metallocene catalysts
(JOHN WILEY & SONS LTDA., 2011)
Polypropylene nanocomposites obtained by in situ polymerization using metallocene catalyst: influence of the nanoparticles on the final polymer morphology
(HINDAWI PUBLISHING CORPORATION, 2012)
Preparation of polypropylene-based nanocomposites using nanosized MCM-41 as support and in situ polymerization
(2016)
MCM-41 nanoparticles were used for preparing nanocomposites through the in situ polymerization of propylene. The performance of the catalytic system and the final properties of the materials obtained are highly dependent ...
