Influence of Linkage Type between Polymer Backbone and Side Groups on Surface Segregation of Methyl Groups During Film Formation

24-Sep-2015 | Yizhi Zhang; Hao Fan; Yuping Wang; Biao Zuo; Wei Zhang; Shunli Wang; XinPing Wang, Soft Matter, 2015

Although poly(vinyl acetate) (PVAc) differs from poly(methyl acrylate) (PMA) only in the reversed position of the ester group, a large difference in the concentration dependence of the casting solution on the corresponding surface structure of the cast films of PVAc, PMA and poly(methyl ...


Using Vinyl Acetate, N‐Hydroxymethyl Acrylamide, and Montmorillonite Intercalated by a Dioctadecyl Dimethyl Ammonium Bromide Surfactant to Prepare Exfoliated Nanocomposite through In Situ Polymerization

21-Sep-2015 | HUI‐WANG CUI, QUN FANG, GUAN‐BEN DU, Advances in Polymer Technology, 2015

ABSTRACT In this study, vinyl acetate, N‐hydroxymethyl acrylamide (NMA), and organic montmorillonite intercalated by a dioctadecyl dimethyl ammonium bromide surfactant (MMT‐DOAB) were used to prepare exfoliated nanocomposites through in situ polymerization. Wide‐angle X‐ray diffraction, ...


Hybridization of CMRP and ATRP: A Direct Living Chain Extension from Poly(vinyl acetate) to Poly(methyl methacrylate) and Polystyrene

14-Sep-2015 | Ya-Jo Chen; Bing-Jyun Wu; Fu-Sheng Wang; Mu-Huan Chi; Jiun-Tai Chen; Chi-How Peng, Macromolecules, 2015

Cobalt-mediated radical polymerization (CMRP) was used to prepare well-defined poly(vinyl acetate) (PVAc) as the macroinitiator in the reverse atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) and styrene (Sty) for the synthesis of block copolymers of PVAc-b-PMMA and ...


Functionalized bicomponent polymer membranes as supports for covalent immobilization of enzymes

13-Sep-2015 | Author(s): Teodor Sandu, Andrei Sarbu, Celina Maria Damian, Delia Patroi, Tanta Verona Iordache, Temenuzhk ..., Reactive and Functional Polymers, 2015

Publication date: Available online 10 September 2015 Source:Reactive and Functional Polymers Author(s): Teodor Sandu, Andrei Sarbu, Celina Maria Damian, Delia Patroi, Tanta Verona Iordache, Temenuzhka Budinova, Boyko Tsyntsarski, M. Ferhat Yardim, Ahmet Sirkecioglu The ...


Exploration of CO2-Philicity of Poly(vinyl acetate-co-alkyl vinyl ether) through Molecular Modeling and Dissolution Behavior Measurement

10-Sep-2015 | Dongdong Hu; Shaojun Sun; Pei-Qing Yuan; Ling Zhao; Tao Liu, Journal of Physical Chemistry B, 2015

Hydrocarbon CO2-philes are of great interest for use in expanding CO2 applications as a green solvent. In this work, multiscale molecular modeling and dissolution behavior measurement were both applied to explore CO2-philicity of the poly(vinyl acetate) (PVAc)-based copolymer. Introduction of a ...


Rhodium‐Catalyzed Direct C–H Vinylation of Arenes To Access Styrenes with Vinyl Acetate as a Vinyl Source

26-Aug-2015 | Shu‐Tao Mei, Kun Jiang, Nan‐Jin Wang, Li Shuai, Yi Yuan, Ye Wei, European Journal of Organic Chemistry, 2015

Abstract RhIII‐catalyzed aryl C–H vinylation for the preparation of styrenes by using vinyl acetate, a commercially available and inexpensive compound, as the vinyl source was successfully realized. This method enables various aromatics including N‐sulfonyl ketimines, pyridines, azoles, and ...


Reverse Iodine Transfer Polymerization of Vinyl Acetate and Vinyl Benzoate: Synthesis and Characterization of Homo‐ and Copolymers

26-Aug-2015 | Mahdi Abdollahi, Poorya Bigdeli, Mahmood Hemmati, Maral Ghahramani, Mohammad Barari, Polymer International, 2015

Abstract Homo‐ and copolymers of vinyl esters including vinyl acetate (VAc) and vinyl benzoate (VBz) were synthesized via reverse iodine transfer radical polymerization (RITP) technique. Polymerization was carried out in the presence of iodine as the in situ generator of the transfer agent and ...


First vinyl acetate mediated organocatalytic transesterification of Phenols: A step towards sustainability

26-Aug-2015 | Manoj Kumar; Sourav Bagchi; Anuj Sharma, New Journal of Chemistry, 2015

The present report outlines our efforts toward a simple yet elegant protocol for O-acylation of wide variety of phenols. This highly enabling and solventless method relies on vinyl acetate as innocuous acyl donor and DABCO as an organocatalyst. Operational simplicity, excellent yields, higher and ...


Pullulan‐Based Polymer Surfactants for Vinyl Acetate Miniemulsion Polymerization: Kinetics and Colloidal Stability Investigations

19-Aug-2015 | Sabrina Belbekhouche, Luc Picton, Didier Le Cerf, Thierry Hamaide, Macromolecular Chemistry and Physics, 2015

Various pullulan‐b‐Jeffamine block copolymers (Jeffamine is a PEO‐b‐PPO copolymer (PEO = poly(ethylene oxide), PPO = poly(propylene oxide)) are used as surfactants for vinyl acetate miniemulsion polymerization. Their influence on the kinetics, average molecular weights and colloidal stability, ...


Synthesis and Rheological Characterization of Poly(vinyl acetate-b-vinyl alcohol-b-vinyl acetate) Triblock Copolymer Hydrogels

30-Jul-2015 | Frank W. Speetjens, II; Mahesh K. Mahanthappa, Macromolecules, 2015

We report the synthesis and shear rheology of a series of hydrogels derived from poly(vinyl acetate-b-vinyl alcohol-b-vinyl acetate) (PVAc-b-PVOH-b-PVAc) triblock copolymers. Bidirectional, reversible-addition–fragmentation chain transfer free radical polymerizations of vinyl acetate (VAc) and ...
