☑ VBC can be used to create polyelectro-lytes with properties applicable to latex electrodeposition on metals. Other VBC-based polymers include polymeric surfactants, flocculating agents, phase transfer catalysts, electron carriers and viologens, ion exchange resins, and polymeric mordants for photographic dyes.
☑ VBC can also make it easier to carry out reactions by acting as a polymeric support. After the molecular synthesis is completed, the modified molecule can be separated from the chloromethyl group. The polymericsupport function of VBC can be used in peptide synthesis.
☑ Used as a polymer reactant, the chloromethyl group of VBC can be modified by substitution of sulfinic acid,nicotinamide, tetrathiafulvalene, fluorinated ketone or amine, azide, oxyvanadium derivatives, Bender’s salt, and many others in place of the chloride.
☑ The chloride of the chloromethyl group of VBC can also be replaced by biochemical, light-absorbent compounds such as chloro-phyll, hemin, porphyrin, and metalloporphyrin to create photosensitive polymers. Using thionine or benzopyran to replace the chloride creates a photochromic polymer. VBC can also be used to create photocon-
ductive polymers.
☑ VBC can be used for a number of analytical applications such as partial resolution of alpha-amino acids, noble metal extraction, uranium recovery, phenol complexing resins, sulfur dioxide removal, copper, cobalt, or mercury complexing, and separation of nucleosides.
☑ VBC can be used to combine and improve the characteristics of elastomers such as improving scorch time, and increasing temperature and weather resistance. It can be used to inhibit elastomer decomposition and even to produce photocurable, water soluble elastomers..
☑ Substituting oxyphosphorated or silicated compounds for the chloride in VBC produces fire-resistant polymers. Similar fire resistance is observed when VBC is copoly-merized with cyclic phosphazene or poly-VBC is cross-linked with stannous chloride, SnCl
☑ Copolymerizing VBC containing a hydroxybenzophenone group with methyl methacrylate produces a transparent,
UV-resistant polymer.
☑ Poly-VBC can be used in lithographic processes because it resists proton and electron beams.
