Dielectric behavior of doped poly (methyl acrylate) (PMA) Conducting polymer has been investigated in electret state. The permittivity and loss factor have been obtained at varying temperatures from 30 to 230C and different frequencies 05,10,25 and 50 kHz for different electrode configurations of doped poly (methyl acrylate) (PMA) conducting polymer films of 25μm thickness. The capacitances are...

This computational study deals with the mechanism of spontaneous initiation in thermal polymerization of alkyl acrylates (e.g., methyl, ethyl, and n-butyl acrylate). The mechanism is presently still unknown. Density-functional theory (DFT) and Møller-Plesset (MP2) calculations are used to explore the Flory and Mayo mechanisms of self-initiation in methyl acrylate. On the singlet surface, a low-...

This computational and theoretical study deals with chain transfer to solvent (CTS) reactions of methyl acrylate (MA), ethyl acrylate (EA), and n-butyl acrylate (n-BA) self-initiated homopolymerization in solvents such as butanol (polar, protic), methyl ethyl ketone (MEK) (polar, aprotic), and p-xylene (nonpolar). The results indicate that abstraction of a hydrogen atom from the methylene group...

Reaction of diarylphosphinobenzene-2-sulfonic acids with tertially amines, followed by addition of [PdMeCl(cod)], provided anionic methylpalladium(II) complexes with bidentate phosphine-sulfonate ligands, which show high activity for copolymerization of ethylene with methyl acrylate.

The benzene ring in the title compound, C(10)H(10)O(4), makes an angle of 4.4 (1)° with the C-C-C-O linker. The hy-droxy groups are involved in both intra- and inter-molecular O-H⋯O hydrogen bonds. The crystal packing is stabilized by O-H⋯O hydrogen-bonding inter-actions. The mol-ecules of the caffeic acid ester form a dimeric structure in a head-to-head manner along the a axis through O-H⋯O hy...

In the title compound, C(12)H(9)NO(4), an important dehydro-amino acid, the acrylate C=C double bond is not parallel to the adjacent carbonyl group and an s-trans configuration is also observed.

Copper methoxide compound IPrCuOMe was unexpectedly formed in a reaction of IPrCuPPh2 with methyl acrylate. The alkoxide product identified from the mixture spectroscopically and structurally characterized. This C–O bond cleavage likely depends on nucleophilicity Cu–P IPrCuPPh2.
