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

15-10-2014 | Xiao-Feng Xia; Zhen Gu; Wentao Liu; Ningning Wang; Haijun Wang; yong-mei Xia; Haiyan Gao; Xiang Liu, Organic & Biomolecular Chemistry, 2014

Arylalkynes can convert into α-diketones by the use of copper catalyst, and also transform into vinyl acetates under metal-free conditions both in the presence of PhI(OAc)2 as oxidant at room temperature. A series of substituted α-diketones were prepared in moderate to good yields. A variety of ...

Growth of White Rot Fungi in Composites Produced from Urban Plastic Waste and Wood

13-10-2014 | André Luis Catto, Eduardo Soares Rosseto, Mateus Arduvino Reck, Katiandry Rossini, Rosa Mara Borges da Silveira, Rut ..., Macromolecular Symposia, 2014

Summary In the search for new biodegradable materials is found the combination of natural fibers with conventional polymeric materials or biodegradable polymers. The incorporation of natural fibers to thermoplastic polymer matrix is associated with improvement of their properties due to ...

Incorporation of high oil content in polyvinyl acetate nanoparticles produced by batch miniemulsion polymerization stabilized with a polymeric stabilizer

22-08-2014 | Fernanda Regina Steinmacher, Pedro Henrique Hermes Araújo, Claudia Sayer, Journal of Applied Polymer Science, 2014

ABSTRACT Nanoparticles (NPs) have been widely applied in the biomedical area. In order to satisfy the requirements for biomedical applications, sodium lauril sulfate (SLS) and hexadecane, widely used as anionic surfactant and co‐stabilizer, were successfully replaced by biocompatible ...

Applying vermiculite‐modified polypropylene film to flexible packaging material

02-06-2014 | YaBo Fu, DongLi Li, WenCai Xu, YingQun Qi, Wei Shang, WeiXia Wu, YaJun Wang, Journal of Applied Polymer Science, 2014

ABSTRACT This article presents a process for preparing organovermiculite by ball‐milling expanded vermiculite (EVMT) in water‐based ethylene vinyl acetate (EVA) latex. In this process, the vermiculite (VMT) is exfoliated to prepare a kind of EVMT/EVA modifying agent, in which EVA serves as ...

Study of the Dynamic Heterogeneity in Poly(ethylene-ran-vinyl acetate) Copolymer by Using Broadband Dielectric Spectroscopy and Electrostatic Force Microscopy

13-09-2013 | Mohammed M. Kummali; Angel Alegría; Luis A. Miccio; Juan Colmenero, Macromolecules, 2013

Dynamic heterogeneities in ethylene–vinyl acetate (EVA) random copolymers were studied using broadband dielectric spectroscopy (BDS) over a broad frequency and temperature range. BDS data for EVA copolymers show relatively broad spectra extending over several frequency decades, which make ...

Dynamic Heterogeneity and Phase Separation Kinetics in Miscible Poly(vinyl acetate)/Poly(ethylene oxide) Blends by Local Dielectric Spectroscopy

12-09-2013 | Tomas P. Corrales; David Laroze; George Zardalidis; George Floudas; Hans-Jürgen Butt; Michael Kappl, Macromolecules, 2013

Local dielectric spectroscopy (LDS) was employed to analyze the miscible blend composed of poly(vinyl acetate) (PVAc) and poly(ethylene oxide) (PEO). The two homopolymers have very different relaxation times and glass transition temperatures. The aim was to study the dynamic heterogeneity in ...

Effect of the Incorporation of Modified Silicas on the Final Properties of Wood Adhesives

23-08-2013 | Audrey Bonnefond, Yury Reyes, Pablo Peruzzo, Erik Ronne, Joanna Fare, Maria Paulis, Jose Ramon Leiza, Macromolecular Reaction Engineering, 2013

The effect of the incorporation of three different surface modified silicas on the final properties of poly(vinyl acetate) (PVAc) latex based wood adhesives is assessed. It is shown that the compatibility and reactivity of the silica with the polymer determines its state of dispersion ...

Polyaniline/ethylene vinyl acetate composites as dielectric sensor

02-08-2013 | Mostafizur Rahaman, Tapan Kumar Chaki, Dipak Khastgir, Polymer Engineering and Science, 2013

The compressive stress (pressure) sensitivity of dielectric properties has been studied on ethylene vinyl acetate (EVA)/polyaniline (Pani) composites prepared through In‐situ synthesis of polyaniline in the solution of insulating EVA matrix. It is observed that the dielectric constant and loss ...

Lightly branched poly(vinyl alcohol) for fluid loss additive

30-07-2013 | Haifeng Han, Junhua Zhang, Journal of Applied Polymer Science, 2013

ABSTRACT One kind of branched Poly(vinyl alcohol) has been synthesized via common radical copolymerization of vinyl acetate in methanol by adding a bifunctional monomer Allyl methacrylate (AMA) followed by saponification. The comonomer AMA has two reactive double bonds that can provide the ...
