The back-bone is an alternating copolymer of methyl vinyl ether
and maleic anhydride.
Some examples of acrylic monomers are 2-ethylhexyl acrylate, butyl acrylate, methyl acrylate, TMPTA, methyl acrylate, ethyl acrylate, 2-chloroethyl vinyl ether
, and hydroxyethyl methacrylate.
Based on high-performance fluoroethylene vinyl ether
(FEVE) resins, PPG Durabrite coating is a direct-to-metal product specially formulated to extend and enrich the beauty of architectural metals by protecting them with a resilient, transparent clearcoat.
PFA is a melt-processable polytetrafluoroethylene with a small amount of perfluoropropyl vinyl ether
(PPVE) added to allow its processing by injection molding.
Triton X-100, Tellurium powder (>96%), Cd[Cl.sub.2] x 2.5[H.sub.2]O (>99%), NaBH4 (96%), cyclohexane (99.9%), and 1-octanol (99%) were obtained from Sinopharm Chemical Reagent Co.; 3-mercaptopropionic acid (MPA, 99%), 6aminocaproic acid (98.5%), and aqueous ammonia solution (30 wt.%) were supplied by Aladdin; polyurethane acrylate (named as WF-106, and the evocating agent is 1173) and Di (ethylene glycol) vinyl ether
were purchased from Haiso Technology Co.
The chemical structure of Aflas PM-1100 and PM- 3000 is derived from tetrafluoroethylene and perfluoroalkyl vinyl ether
, which is said to offer superior resistance to chemicals, oils and solvents.
Fluoropolymers that are used as binders in coatings include polytetrafluoroethylene (PTFE, or Teflon[R]), fluorinated ethylene propylene (FEP), ethylene tetrafluoroethylene copolymer (ETFE), polyvinylfluroide (PVF), polyvinylidene fluoride (PVDF), and fluoroethylene vinyl ether
Abstract Novel, partially bio-based poly(vinyl ether
) copolymers derived from soybean oil and cyclohexyl vinyl ether
(CHVE) were produced by cationic polymerization and investigated for application as alkyd-type surface coatings.
Methyl benzoate (Fluka AG >0.996), tetrahydrofuran, 1,4-dioxane, anisole, and butyl vinyl ether
(all Sigma-Aldrich, AR grade) of mass purity >0.997 were used without further purification.
Polymers such as perfluoroalkoxy copolymer, a copolymer of tetrafluoroethylene and perfluoro(alkyl vinyl ether
), and fluorinated ethylene propylene, a copolymer of hexafluoropropylene and tetrafluoroethylene, have found only limited use in blow-molding applications because of low melt strength.
Further studies were published by Lu et al in 19532 which led to the clinical use of trifluoroethyl vinyl ether
(fluroxene or "Fluoromar"), but its potential flammability was a disadvantage and it enjoyed only limited acceptability.
(5,6) Studies on systems containing a stoichiometric balance of maleate and vinyl ether
functional groups have been previously reported.
