STYRENE/STYRENE-DERIVATIVE COPOLYMERIZATION BY PH2Zn-METALLOCENE-MAO SYSTEMS: HOMO- AND COPOLYMERIZATION OF á-METHYLSTYRENE WITH STYRENE
(Sociedad Chilena de Química, 2010)
New architecture of supported metallocene catalysts for alkene polymerization
(John Wiley & Sons Inc, 2007-12)
We report the synthesis of a supported metallocene catalyst that exhibits the same activity as a homogeneous catalyst for ethylene polymerization reactions. The key to this new catalytic system is a hybrid organic-inorganic ...
STUDY OF THE EFFECT OF BRANCHING IN DEGRADATION OF POLYETHYLENES OBTAINED VIA METALLOCENE CATALYST
(Sociedad Chilena de Química, 2008)
Study of the polymerization of 1-octadecene with different metallocene catalysts
(SPRINGER-VERLAG, 2002-12)
1-Octadecene (C18) was polymerized by using different metallocene catalysts. The rac-Et(Ind)(2)ZrCl2/MAO (I) and rac-Me2Si(Ind)(2)ZrCl2/MAO (III) presented the highest C, activity as compared with rac-Et(2-Me-Ind)(2)ZrCl2/MAO ...
Viscoelastic relaxations in poly(ethylene-co-1-octadecene) synthesized by a metallocene catalyst
(ELSEVIER SCI LTD, 2002-12)
The viscoelastic relaxations of four copolymers of ethylene and I-octadecene, with different comonomer contents, synthesized with a metallocene catalyst, have been analysed and compared to those of the corresponding ...
Study of the catalytic species metallocene/MAO and metallocene/TMA by cyclic voltammetry
(Elservier, 2004)
In this paper, an electrochemical study of the metallocene/methylaluminoxane (MAO) and metallocene/trimethylaluminium (TMA) species
is presented. The metallocenes used were [(CH3)2Si(Cp)2ZrCl2] and [(Cp)2ZrCl2]. The ...
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 ...
Study of metallocene supported on porous and nonporous silica for the polymerization of ethylene
(1997)
Porous and nonporous silicas are good supports for the synthesis of coordinative heterogeneous catalysts for ethylene polymerization. The catalytic activity of nonporous Aerosil depends critically on the percentage of ...
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 ...
