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 ...

A Unique Double Percolated Polymer Composite for Highly Efficient Electromagnetic Interference Shielding

16-Jun-2016 | Li‐Chuan Jia, Ding‐Xiang Yan, Cheng‐Hua Cui, Xu Ji, Zhong‐Ming Li, Macromolecular Materials and Engineering, 2016

This study has developed a carbon nanotube (CNT)/ethylene vinyl acetate (EVA)/ultrahigh molecular weight polyethylene (UHMWPE) composite with a unique double percolated conductive structure, in which only 20 wt% of CNT enriched EVA is needed to form a continuous conductive network. Compared with ...

A Simple and Efficient Method for the Synthesis of Novel Pyrazolyl Isoxazoline Derivatives Using Hypervalent Iodine (III) Reagent

09-Jun-2016 | Rajesh Kumar, Manoj Kumar, Om Prakash, Heteroatom Chemistry, 2016

Abstract A series of novel pyrazolyl isoxazolines were synthesized by 1,3‐dipolar cycloaddition of pyrazolyl nitrile oxide with various activated alkene, such as acrylonitrile, methyl acrylate, and vinyl acetate, in the presence of iodobenzene diacetate in methanol containing a catalytic ...

Functional modification of poly(vinyl alcohol) by copolymerizing with a hydrophobic cationic double alkyl‐substituted monomer

30-May-2016 | Jiaojiao Ma, Xiande Yin, Hongqin Xiao, Ying Li, Jianjun Bao, Journal of Applied Polymer Science, 2016

ABSTRACT In this paper, a hydrophobic monomer (HM) that has a cationic double alkyl‐substituted group bonded to the nitrogen atom was first synthesized. Then a hydrophobic poly(vinyl alcohol) (PVA) was prepared by a radical solution copolymerization of vinyl acetate (VAc) with the HM followed ...

Prediction of diffusion in a ternary solvent–solvent–polymer blend by means of binary diffusion data: Comparison of experimental data and simulative results

30-May-2016 | David Siebel, Philip Scharfer, Wilhelm Schabel, Journal of Applied Polymer Science, 2016

ABSTRACT Multicomponent diffusion of solvents in polymeric systems is not completely understood, despite many scientific contributions to the topic. Literature scarcely offers measurement data on diffusion for model validation in such systems. In this work, the ternary systems consisting of ...

Short-Chain Branched Polar-Functionalized Linear Polyethylene via “Tandem Catalysis”

26-May-2016 | Zhongbao Jian; Stefan Mecking, Macromolecules, 2016

Cationic PdII complex 1 chelated by an N-fixed phosphine sultam has been synthesized and structurally characterized. Exposure of 1 to ethylene resulted in the formation of short-chain olefins (1-butene: 2-butene: 1-hexene: 1-octene = 86:7:6:1) with a high catalytic activity of 105 molE molPd–1 ...
