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 ...

Proteomic Analysis of Nuclei Dissected from Fixed Rat Brain Tissue Using Expression Microdissection

19-07-2013 | A. R. Blackler; N. Y. Morgan; B. Gao; L. R. Olano; M. D. Armani; E. Romantseva; J. W. Kakareka; R. F. Bonner; S. Muk ..., Analytical Chemistry, 2013

Expression microdissection (xMD) is a high-throughput, operator-independent technology that enables the procurement of specific cell populations from tissue specimens. In this method, histological sections are first stained for cellular markers via either chemical or immuno-guided methods, placed ...

Reversible addition‐fragmentation chain‐transfer polymerization of vinyl monomers with N,N‐dimethyldiselenocarbamates

17-07-2013 | Dimitri Matioszek, Oleksii Brusylovets, D. James Wilson, Stéphane Mazières, Mathias Destarac, Journal of Polymer Science Part A: Polymer Chemistry, 2013

ABSTRACT A new range of selenium‐based reversible addition‐fragmentation chain‐transfer (RAFT) agents is described and tested in the polymerization of styrene, acrylates, vinyl esters, and N‐vinylcaprolactam. The synthesized N,N‐dimethyldiselenocarbamates were poor control agents for styrene ...

Controllable synthesis of a novel poly(vinyl alcohol)‐based hydrogel containing lactate and PEG moieties

10-07-2013 | Jing Xu, Congming Xiao, Xuelei He, Polymer Engineering and Science, 2013

Tunable hydrogel that contained well‐defined poly(vinyl alcohol) (PVA), labile lactate groups, and hydrophilic poly(ethylene glycol) (PEG) segments was prepared through a combination of reversible addition‐fragmentation chain transfer (RAFT) polymerization and esterification reaction. A diol was ...
