Rhodium-Catalyzed β-Selective Oxidative Heck-Type Coupling of Vinyl Acetate via C-H Activation.
Organic Letters, 2016An efficient Rh(III)-catalyzed direct ortho-C-H olefination of acetanilides with vinyl acetate was developed. This protocol provides a straightforward pathway to a series of (E)-2-acetamidostyryl acetates, giving access to indole derivatives following a ...

Abstract The dependence of thermal degradation behaviour on vinyl acetate (VA) content of ethylene-vinyl acetate (EVA) copolymers was studied by thermogravimetric analysis (t.g.a.). Among the parameters investigated, the maximum rate of weight loss at the stage of acetic acid evolution was found to have a linear relationship with VA content and to be

Vinyl acetate and vinyl alcohol copolymers with tetrafluoroethylene
European Polymer Journal, 1967Abstract Vinyl acetate-tetrafluoroethylene copolymerization is described; copolymers containing up to 20 per cent fluorine by weight have been synthetized and hydrolysed. Their structure is random as established by i.r. and X-ray analysis and by degradative oxidation. The variation of solubility with the composition of the copolymers is reported. The

Abstract Isobaric (vapour+liquid) equilibria were determined at p =101.3 kPa for (methanol+butyl acetate), (methanol+isobutyl acetate), (vinyl acetate+butyl acetate), and (vinyl acetate+isobutyl acetate). The thermodynamic consistency of the experimental data was checked by using a modified Dechema test. The activity coefficients were correlated with

Diffusion coefficient and solubility of vinyl acetate molecules in poly(vinyl acetate) matrices
European Polymer Journal, 1992Abstract Diffusion coefficient and equilibrium solubility for poly(vinyl acetate)/vinyl acetate system (VAc) were determined by measuring the rate of uptake or loss of VAc. The amount of residual VAc, as well as temperature, affected the mutual diffusion coefficient. Free volume theory, proposed recently by Vrentas and Duda, represented the behaviour

Carbon‐13 NMR of poly(vinyl acetate) and ethylene–vinyl acetate copolymer
Journal of Polymer Science: Polymer Physics Edition, 1981AbstractCarbon‐13 nuclear magnetic resonance spectra of atactic poly(vinyl acetate) and ethylene–vinyl acetate copolymers are reported and analyzed. Carbon spectra at 22.6 and 62.9 MHz together with use of shift reagents have permitted a more complete assignment than previously reported; in some cases the published assignments are found to be in error.

AbstractThe synthesis of vinyl phenyl acetate, by an ester interchange reaction between phenyl acetic acid and vinyl acetate and utilizing a catalyst, is described. Copolymerization with vinyl chloride, in a suspension system and using a peroxide catalyst, is described on a laboratory and pilot plant scale.
