1, monomer synthesis involves transesterification of a plant oil with 2-(vinyloxy)ethanol (2-VOE) to produce a vinyl ether
monomer that possesses fatty acid ester chains derived from the plant oil.
REAL TIME INFRARED SPECTROSCOPY: Real-time IR was used to study the disappearance of the vinyl ether
peak at 1639 [cm.
For most carbocationic polymerizations of a vinyl ether
produced using a Lewis Acid coinitiator, such as ethylaluminum sesquichloride, an appropriate concentration of Lewis base is needed to obtain a living polymerization.
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.
Very few nanocomposites originating from vinyl ether
monomers were mentioned in the literature.
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.
ep] are the contributions to the rate of reaction attributed to vinyl ether
and cyclo epoxy monomers, respectively, and [[alpha].
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.
0 to 10% weight, relative to the total weight of the composition, of a photoinitiator; and five to 50% weight, relative to the total weight of the composition, of one or more monofunctional diluents selected from the group consisting of alkyl (meth)acrylate monomers, N-vinyl functional diluents, and vinyl ether
functional diluents; wherein the composition, after cure, has a dielectric dissipation factor at 60 Hz and 150[degrees]C of lower than about 0.
The insolubilization temperature of the resists and conversion of vinyl ether
groups are greatly influenced by the PAG concentration and prebaking temperature, respectively.
Consequently, only the conversion of the vinyl ether
component in cationic formulations can be determined by NIR spectroscopy.
