Oxygen Atom Is Part Of Ether Or Hydroxyl Group Patents (Class 526/307.5)
  • Patent number: 7060773
    Abstract: This invention relates to the reversible protection of hydroxy-silane functional groups by acid cleavable protecting groups. The development of reversible protecting groups greatly enhances the current utility of silanes while introducing further novel applications. For instance, reversibly protected silanes are of particular value in applications where room temperature cure and/or adhesion is of value, such as coatings, high resolution imaging, caulks, adhesives, sealents, gaskets, and silicones. Reversibly protected silanes can also be beneficially used in reticulating agents, and in sizing agents, tires, and release coatings. The incorporation of reversibly protected silanes into coating resins is of particular value. The reversibly protected silane can be incorporated into the coating resin by polymerizing a monomer containing the reversibly protected silane into the resin or by post-addition into the coating formulation.

  • Patent number: 6962962
    Abstract: The invention provides an optically active polymer which is a product obtained by polymerizing a chiral alkoxy-substituted phenylacetylene such as p-(2-methylbutoxy)phenylacetylene, of which the 2-methylbutoxy group has chirality, in an organic solvent such as triethylamine in the presence of a rhodium complex compound as a polymerization catalyst. The optically active polymer exhibits a much larger optical rotation than the monomeric compound per se and is colored in different colors of, e.g., yellow and black, depending on the organic solvent used for polymerization. The yellow polymer turns to black by exposure to the vapor of a specific organic solvent such as chloroform and returns to yellow by re-precipitation from a chloroform solution with addition of methyl alcohol as a precipitant.

  • Patent number: 6455655
    Abstract: This invention discloses an emulsion styrene-butadiene rubber (SBR) that can be employed in manufacturing tire tread formulations that have rolling resistance and treadwear characteristics that are similar to those made with solution SBR but with improved traction characteristics. Thus, the emulsion SBR of this invention is superior in many respects for use in tire tread compounds to conventional solution SBR and conventional emulsion SBR. This invention more specifically discloses a styrene-butadiene rubber composition which is comprised of repeat units which are derived from styrene, 1,3-butadiene, and a hydroxy alkyl acrylate monomer, wherein the styrene-butadiene rubber composition has a number average molecular weight as determined by field flow fractionation which is within the range of about 50,000 to 150,000, and wherein the styrene-butadiene rubber has a light scattering to refractive index ratio which is within the range of 1.8 to 3.9.
