ChemInform Abstract: Selective Oxygenation of Alkynes: A Direct Approach to Diketones and Vinyl Acetate.

09-Apr-2015 | Xiao‐Feng Xia, Zhen Gu, Wentao Liu, Ningning Wang, Haijun Wang, Yongmei Xia, Haiyan Gao, Xiang Liu, ChemInform, 2015

Abstract Arylalkynes can be selectively converted into α‐diketones under copper catalysis, and also into vinyl acetates under metal‐free conditions, using PhI(O‐Ac)2 as oxidant.

Evaluation of the efficiency of copolymers of methyl methacrylate and vinyl acetate synthesized by emulsion polymerization for control of aqueous filtrate loss

28-Mar-2015 | Rita de Cassia P. Nunes, Renata V. Pires, Elizabete F. Lucas, Journal of Applied Polymer Science, 2015

ABSTRACT One of the main problems faced while drilling oil wells is loss of fluid to the rock formation. This loss can be reduced with the use of chemical additives called filtrate controllers, which must be tailored to the specific characteristics of the rock formation and drilling ...

Ethylene vinyl acetate blends with cellulosic fillers and reinforcements

28-Mar-2015 | Luciana Sartore, Alberto D'Amore, Luca Di Landro, Polymer Composites, 2015

Polymeric blends based on ethylene vinyl acetate (EVA) rubbers filled with high molecular weight carboxymethyl cellulose were investigated in view of possible employment as biodegradable materials. The effect of vinyl acetate (VA) content and of addition of transesterification agent to increase ...

Encapsulation of PV Modules Using Ethylene Vinyl Acetate Copolymer as the Encapsulant

27-Mar-2015 | Shan Jiang, Kemin Wang, Hongwen Zhang, Yonghong Ding, Qiang Yu, Macromolecular Reaction Engineering, 2015

Ethylene vinyl acetate (EVA) encapsulation materials have attracted a lot of attention due to their extensive applications in solar cells. Nearly 80% of photovoltaic (PV) modules are encapsulated by EVA materials. EVA has lots of advantages, such as good light transmittance and elasticity, low ...

Preparation and characterization of biodegradable polymer blends from poly(3‐hydroxybutyrate)/poly(vinyl acetate)‐modified corn starch

26-Mar-2015 | Sun‐Mou Lai, Wei‐Wei Sun, Trong‐Ming Don, Polymer Engineering and Science, 2015

Biodegradable polymer blends prepared by blending poly(3‐hydroxybutyrate) (PHB) and corn starch do not form intact films due to their incompatibility and brittle behavior. For improving their compatibility and flexibility, poly(vinyl acetate) (PVAc) was grafted from the corn starch to prepare ...

Detection of decomposition for high pressure ethylene/vinyl acetate copolymerization in autoclave reactor using principal component analysis on heat balance model

16-Mar-2015 | G Sivalingam, Nipun J. Soni, Suketu M. Vakil, The Canadian Journal of Chemical Engineering, 2015

Abstract The autoclave reactor offers flexibility in producing specialty grades of ethylene/vinyl acetate copolymer at temperature range of 150‐230 °C and pressure range of 1400‐2000 kg/cm2. At such conditions, copolymerization is accompanied by decomposition of reactants which increases the ...

Synthesis and characterization of new vinyl acetate grafting onto epoxidized linseed oil in aqueous media

03-Mar-2015 | Mohamed Jebrane, Shengzhen Cai, Dmitri Panov, Xi Yang, Nasko Terziev, Journal of Applied Polymer Science, 2015

ABSTRACT Modified poly (vinyl acetate) copolymers with epoxidized linseed oil (ELO) as co‐monomer have been prepared. The polymerization was performed in aqueous medium without any additional protective colloid in the presence of sodium persulfate as catalyst. The effect of vinyl acetate ...

The effect of expanded graphite on the thermal stability, latent heat, and flammability properties of EVA/wax phase change blends

26-Feb-2015 | M.J. Mochane, A.S. Luyt, Polymer Engineering and Science, 2015

This article reports on the morphology, melting and crystallization behavior, thermal stability, flammability and thermal conductivity of shape‐stabilized phase‐change materials (PCM) for thermal energy storage, based on a soft Fischer–Tropsch paraffin wax, the PCM, blended with ethylene vinyl ...
