This result shows that the diluent Di (ethylene glycol)
vinyl ether in the inks intensively affects the mechanical strength of resultant resin.
Since the menthol
vinyl ether monomer is not commercially available, it was of interest to produce and characterize coatings derived from copolymers of 2-VOES and a commercially available
vinyl ether monomer that could substantially increase copolymer [T.sub.g] compared to that of poly(2-VOES).
The dielectric constants of methyl benzoate, tetrahydrofuran, 1,4-dioxane, anisole, and butyl
vinyl ether are [member of] = 6.02, 7.261, 2.209, 4.33, 3.9, respectively.
The change in
vinyl ether conversion as a function of different UV exposure times is illustrated in Figure 2.
The
vinyl ether silane was prepared according to the patent (34).
Using simple base-catalyzed transesterification of a
vinyl ether alcohol with either a plant oil triglyceride or fatty alkyl ester, a novel
vinyl ether monomer was produced.
Typical examples include coatings made from aqueous dispersions polytetrafluoroethylene (PTFE), tetrafluoroethylene/hexafluoroethylene copolymers (FEP), and tetrafluoroethylene/perfluoroalkyl
vinyl ether copolymers (PFA) for non-stick and anti-corrosion applications.
6 was expressed as the sum of the two distinct contributions attributed to
vinyl ether and cyclo epoxy monomers, as reported in Eq.
All of the formulations used in the demonstration contained Ashland Advantage 4910 polymer, and one or more polyvinylpyrrolidone (PVP) based copolymers, Aquaflex polymers or Gantrez methyl
vinyl ether and maleic acid (PVM/MA) copolymers that bring additional styling and hold benefits, such as stiffness, shine, climate control, touchable hold, style longevity or improved curl memory--attributes that keep hair spray a go-to styling aid, representing $3 billion a year business.
"Linear
vinyl ether polymers with narrow molecular weight distributions were obtained from novel
vinyl ether monomers derived from a variety of renewable resources including plant oils, eugenol, and cardanol," said Chisholm.
The charge transfer complex (CTC) system consisting of maleic anhydride (MAH), vinyl acetate (VAC), butyl
vinyl ether (BVE), or N-vinyl pyrrolidone (NVP) containing high reactive group was used to graft with polymeric films.
The insolubilization temperature of the resists and conversion of
vinyl ether groups are greatly influenced by the PAG concentration and prebaking temperature, respectively.
