Methyl Internal Rotation in the Microwave Spectrum of Vinyl Acetate

10-12-2014 | Ha Vinh Lam Nguyen; Atef Jabri; Vinh Van; Wolfgang Stahl, Journal of Physical Chemistry A, 2014

The rotational spectrum of vinyl acetate, CH3(CO)OCH═CH2, was measured using two molecular beam Fourier transform microwave spectrometers operating in the frequency range from 2 to 40 GHz. Large splittings up to 2 GHz occurred due to the internal rotation of the acetyl methyl group CH3CO with a ...

Liquid–Liquid Equilibrium for Ternary System Methanol + Methyl Acetate + 1,3-Dimethylimidazolium Dimethylphosphate at Several Temperatures and Atmospheric Pressure

04-12-2014 | Fufeng Cai; Jessica Juweriah Ibrahim; Lei Niu; Wei Xu; Guomin Xiao, Journal of Chemical & Engineering Data, 2014

The azeotrope methanol and methyl acetate is involved in the industrial manufacturing process of vinyl alcohol which is made from vinyl acetate by alcoholysis with methanol. This work focused on a study of ionic liquid as a solvent in the extraction separation for this azeotropic mixture. The ...

Effect of acetylation on the physico‐chemical properties of Indian Horse Chestnut (Aesculus indica L.) starch

26-11-2014 | Shubeena Akhter, Idrees Ahmed Wani, Adil Gani, Paras Sharma, Touseef Ahmed Wani, Farooq Ahmad Masoodi, Afshan Hamdan ..., Starch - Stärke, 2014

The present work was carried out to study the effect of acetylation (0, 3, 6 and 9 g vinyl acetate/gram starch) on the physico‐chemical properties of starch, isolated from Indian horse chestnut (Aesculus indica). Work on starch acetylation and characterization from Indian horse chestnut has not ...

Effect of Head-To-Head Addition on Vinyl Acetate Propagation Kinetics in Radical Polymerization

21-11-2014 | Otlaatla Monyatsi; Anatoly N. Nikitin; Robin A. Hutchinson, Macromolecules, 2014

The radical propagation kinetics of vinyl acetate (VAc) has been studied by pulsed-laser polymerization coupled with analysis of the resulting polymer molar mass distributions. The significant increase in the apparent propagation rate coefficient observed with increasing pulse repetition rate is ...

Triple‐Shape Effect with Adjustable Switching Temperatures in Crosslinked Poly[ethylene‐co‐(vinyl acetate)]

10-11-2014 | Ulrich Nöchel, Uttamchand Narendra Kumar, Ke Wang, Karl Kratz, Marc Behl, Andreas Lendlein, Macromolecular Chemistry and Physics, 2014

A triple‐shape capability of copolymer networks enabling a variation of the two switching temperatures Tsws by purely physical functionalization is introduced. The polymer networks obtained by covalently crosslinking of poly[ethylene‐co‐(vinyl acetate)] exhibit a broad melting transition. The ...

Compatibilization of PUR/PVAC polymer blend by addition of calcium carbonate filler

04-11-2014 | Domagoj Vrsaljko, Xujin Bao, Polymer Composites, 2014

The influence of untreated and stearic acid surface pretreated calcium carbonate (CaCO3) nanofiller (U1 – untreated CaCO3 and U1S2 – stearic acid treated CaCO3) on the properties of polyurethane/poly(vinyl acetate) (PUR/PVAC) polymer blends was investigated. Adhesion between fillers and polymers ...

Cobalt Bipyridine Bisphenolate Complex in Controlled/Living Radical Polymerization of Vinyl Monomers

29-10-2014 | Yi-Chien Lin; Yi-Liang Hsieh; Yuan-Deng Lin; Chi-How Peng, Macromolecules, 2014

Cobalt(II) bipyridine bisphenolate (CoII(BpyBph)) was applied to mediate the controlled/living radical polymerization of vinyl acetate (VAc), methyl acrylate (MA), and other vinyl monomers such as N-vinylpyrrolidone (NVP) and acrylonitrile (AN). The living characters of linear increased molecular ...

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 ...
