Thermal properties of ethylene octene copolymer (Engage)/ dimethyldioctadecyl quaternary ammonium chloride-modified montmorillonite clay nanocomposites
The nanocomposites of ethylene octene copolymer (Engage ) with an organically modified (dimethyldioctadecyl quaternary ammonium chloride) montmorillonite (M-MMT) clay were synthesized by using a solution intercalation technique. The intercalation of M-MMT layers for M-MMT loading of 2.5–7.5% was verified by the shift of X-ray diffraction peak to a lower angle, showing change in basal d-spacing ...
متن کاملCrystallization, Melting Behavior, Physical Properties, and Physical Aging of Ethylene/1-Octene Copolymers
The time dependence of the physical properties of ethylene/1-octene (EO)-copolymers after primary crystallization is investigated by calorimetry, density, and creep measurements. The temporal evolution of the multiple melting of EO-copolymers is monitored by differential scanning calorimetry. The low temperature endotherm displays an evolution similar to that observed for the enthalpy recovery ...
متن کاملPreparation and Mechanical Properties of Compositionally Graded Polyethylene/Clay Nanocomposites
This paper presents the preparation and mechanical properties of compatibilized compositionally graded Polyethylene/ low density polyethylene (LDPE)/ modified montmorillonite (MMT) nanocomposites prepared by solution and melt mixing techniques. Use of polyethylene glycol as compatibilizer improves compatibility of modified montmorillonite and low density polyethylene. Comparisons between two t...
متن کاملPreparation of "Constrained Geometry" Titanium Complexes of [1,2]Azasilinane Framework for Ethylene/1-Octene Copolymerization.
The Me₂Si-bridged ansa-Cp/amido half-metallocene, [Me₂Si(η⁵-Me₄C₅)(NtBu)]TiCl₂, termed a "constrained-geometry catalyst (CGC)", is a representative homogeneous Ziegler catalyst. CGC derivatives with the [1,2]azasilinane framework, in which the amide alkyl substituent is joined by the Si-bridge, were prepared, and the catalytic performances of these species was studied. Me₄C₅HSi(Me)(CH₂CH=CH₂)-N...
متن کاملMorphology and Mechanical Properties of Binary Blends of Polypropylene with Statistical and Block Ethylene-Octene Copolymers
In the present work, statistical (EOCs) and block (OBCs) ethylene-octene copolymers, with similar densities and crystallinities, were used as impact modifiers of isotactic polypropylene (iPP), and the toughening effects of these two types of elastomers were compared. The viscosity curves of EOCs were similar to those of OBCs with equivalent melt flow rate (MFR), enabling a comparison of the vis...
