  • Patent number: 6995225
    Abstract: A proton conduction material having high proton conductivity and exhibiting high reactive gas permeability regardless of the percentage of water content is provided. This proton conduction material consists of a polymer material whose molecular structure has a strong acid functional group. This polymer material consists of a polymer of a mixture of a monomer having an end structure expressed by a formula (1) or a vinyl radical and a monomer expressed by a formula (2). A strong acid functional group is included in the structure of both the monomers. It is to be noted herein that R1, R2, R3, R4, R5 and R6 represent a hydrocarbon radical, a fluoro-substituted hydrocarbon radical, or a trimethylsiloxy radical. Because introduction of a structure in which a hydrocarbon radical is bonded to silicon weakens interaction and causes bulkiness, gaps are created among atoms. If the number of the gaps among the atoms increases, the diffusion coefficient of reactive gases increases.

  • Patent number: 6852816
    Abstract: Polymers may be made from zwitterionic monomers having controlled architectures and molecular weights, using living polymerisations such as group or atom transfer radical polymerisation. For instance polymers may be formed by atom transfer radical polymerisation using a copper chloride catalyst, a ligand which is water soluble, and a water soluble tertiary alkyl halide initiator to form homopolymers having controlled polydispersities of less than 1.5 and block copolymers with other hydrophilic or hydrophobic monomers. One suitable zwitterionic monomer is 2-methacryloyloxy-2?-trimethylammoniumethyl phosphate inner salt. The block copolymers may spontaneously form micelles, believed to have zwitterionic, for instance phosphorylcholine, groups at the external surface, which may be useful as drug delivery systems with improved biocompatibility.

    Abstract: Copolymers of zwitterionic monomer, especially 2-methacryloyloxyethyl-2?-trimethylammoniumethyl phosphate inner salt, and hydrophobic comonomer, especially dodecylmethacrylate, are made in a monomer starved polymerization process in which solutions of monomers are fed to the reaction vessel in which initiator is present over an extended period. The copolymers have improved compositional uniformity and provide better coatings on a range of substrates. The novel copolymers can be distinguished from prior art batch type bulk solution polymerization polymers of the same monomer composition by solubility characteristics especially in alcohol/water mixtures. Particularly preferred coating compositions comprise an alcohol:water mixture containing around 20 to 40% by volume alcohol.
