Carbon nanotubes‐polymer nanocomposites for controlled heating materials

13-Aug-2016 | Adam Januszko, Jerzy Peszke, Urszula Jaworska, Agnieszka Pawlicka, Journal of Applied Polymer Science, 2016

ABSTRACT Nanocomposites of modified carbon nanotubes (CNT) and either polyurethane (PU), poly(vinyl acetate) (PVAc), or silicone materials were synthetized and characterized for thermal mat application. The obtained results revealed that the polymer used as a matrix had an impact on the ...

Influence of dynamic crosslinking on the morphology, crystallization, and dynamic mechanical properties of PA6,12/EVA blends

03-Aug-2016 | Fabrício Bondan, Juliano Roberto Ernzen, Javier Amalvy, Ana Vera Machado, Johnny De Nardi Martins, Otávio Bianchi, Journal of Applied Polymer Science, 2016

ABSTRACT This study investigated the effect of dynamic crosslinking of polyamide 6,12 and random copolymers of ethylene and vinyl acetate blends (PA6,12/EVA) on the morphology, crystallinity, and dynamic mechanical properties. The crosslinking agent was dicumyl peroxide (DCP), and the blends ...

Effect of organic montmorillonite on microstructure and properties of the OMMT/EVA/Asphalt composites

18-Jul-2016 | Xin Yan Xiao, Wu Liu, Deng Ke Zhang, Cai Xia Wan, Polymer Composites, 2016

In order to improve the aging resistance and rutting resistance of the asphalt, a novel OMMT/EVA/asphalt composite was prepared by using organic montmorillonite (OMMT) and ethylene vinyl acetate (EVA) as modifiers via melt blending method. The microstructure and morphology of the EVA/asphalt ...

Theoretical Study of Reactions between Oxygen‐Centered Radicals (•OH and SO4•—) and Vinyl Monomers in Aqueous Phase

14-Jul-2016 | Julibeth M. Martinez‐De la Hoz, Ivan A. Konstantinov, Steven G. Arturo, Gary Dombrowski, Macromolecular Theory and Simulations, 2016

In this work, reactions between industrially relevant monomers (methyl acrylate, ethyl acrylate, methyl methacrylate, vinyl acetate, and isopropenyl acetate) and oxygen‐centered radicals (•OH and SO4 •—) are studied using a combination of quantum mechanics and transition state theory. These ...

Bulk Free Radical Polymerization of Methyl Methacrylate and Vinyl Acetate: A Comparative Study

11-Jul-2016 | David Victoria‐Valenzuela, Jorge Herrera‐Ordonez, Gabriel Luna‐Barcenas, George D. Verros, Dimitris S. Achilias, Macromolecular Reaction Engineering, 2016

The model and methodology for estimating diffusion‐controlled rate coefficients for the methyl methacrylate (MMA) polymerization system is extended to the vinyl acetate (VAc) case. Comparison of the kinetic behavior and termination rate coefficients (kt) of both monomers suggests that at low ...

Thermal stability and flammability of ethylene vinyl acetate copolymers in presence of nanoclay and a halogen‐free flame retardant

23-Jun-2016 | Mehdi Entezam, Hossein Ali Khonakdar, Seyed Mohammad Ali Jafari, Said Raji, Maryam Otadi, Journal of Vinyl and Additive Technology, 2016

In this study, thermal stability behavior and flammability of ethylene‐vinyl‐acetate (EVA) copolymers containing organo‐modified nanoclay particles (Cloisite 15A) and ammonium polyphosphate (APP) along with pentaerythritol (PER), as halogen‐free flame retardants, were investigated. Transmission ...
