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 ...

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 ...
