Morphological, mechanical and rheological properties of nylon 6/acrylonitrile-butadiene-styrene blends compatibilized with MMA/MA copolymers
The morphological, mechanical and rheological properties of nylon 6/acrylonitrile-butadiene-styrene blends compatibilized with MMA-MA [poly(methyl methacrylate-comaleic anhydride)] copolymers were studied. A twin screw ...
Theoretical analysis of nitroxide-mediated copolymerization of styrene and a-methyl-styrene under different operating policies and reactor designs
(Wiley VCH Verlag, 2013-05-27)
The polymerization that IUPAC terms reversible-deactivation radical polymerization is a controlled radical polymerization technique (CRP) that allows producing polymers with tailored properties without the stringent ...
Thermal treatment of the carbon nanotubes and their functionalization with styrene
(Elsevier Science, 2009-07)
In this work we studied the functionalization of commercially available multiwalled carbon nanotubes (MWCNT) (Nanocyl 3100) with polystyrene by the method so called "grafting from". The nanotubes were used as received and ...
Effect of the preparation method on the properties of hematite-based catalysts with lanthanum for styrene production
The influence of the preparation method on the properties of lanthanum-doped hematite prepared with potassium carbonate was studied aiming to get catalysts for styrene production from ethylbenzene dehydrogenation. The most ...
Effect of the composition and chemical aging in tung oil-styrene networks: Free volume and dynamic-mechanical properties
(Pergamon-Elsevier Science Ltd., 2016-12-16)
A study on the effect of the composition and chemical aging in tung oil-styrene networks prepared by cationic polymerization is presented. To this aim, the experimental techniques positron annihilation lifetime spectroscopy ...
Characterization of surface NH3+Cl- groups on poly (styrene-co-Boc-amino styrene) microspheres obtained by controlled acidic treatment
(Academic Press Inc Elsevier ScienceSan DiegoEUA, 2004)
Kinetic study of the selective hydrogenation of styrene over a Pd egg-shell composite catalyst
This is a study on the kinetics of the liquid-phase hydrogenation of styrene to ethylbenzene over a catalyst of palladium supported on an inorganic–organic composite. This support has a better mechanical resistance than ...
Controlling Nanodomain Morphology of Epoxy Thermosets Modified with Reactive Amine-Containing Epoxidized Poly(styrene-b-isoprene-b-styrene) Block Copolymer
(American Chemical Society, 2014-10)
Controlling nanodomain morphology of nanostructured epoxy thermosets is critical to modulate the mechanical properties of the cross-linked matrix. In this contribution, we demonstrate that this can be achieved by using a ...
Methoxycarbonylation of Styrene Using a New Type of Palladium Complexes Bearing P,N-donor Ligands as Catalysts
Palladium complexes of the type [Pd(L)Cl(PPh3)]Cl (L = 2-diphenylphosphinoamino)pyrimidine, or 2-diphenylphosphinoaniline), generated in situ by addition of one equivalent of PPh3 to the corresponding neutral complexes ...
