At Least One Solid Polymer Derived From Ethylenic Reactants Only Patents (Class 524/40)
  • Patent number: 4407990
    Abstract: An acrylic coating composition suitable for use as an automotive refinish lacquer comprises a mixture of(a) a solution in volatile organic solvent of an acrylic copolymer of 75-90% methyl methacrylate, 1.5-6.0% dimethylaminoethyl methacrylate and 8-23.5% of butyl acrylate, butyl methacrylate or lauryl methacrylate, the copolymer having a Tg of 80.degree.-95.degree. C.;(b) a solution in volatile organic solvent of cellulose acetate butyrate, the cellulose acetate butyrate having a viscosity of 0.5-5 sec and a hydroxyl value of 2 maximum; and(c) a monomeric ester plasticizersuch that the non-volatile constituents of (a), (b) and (c) comprise respectively 43.5-64.0%, 15.0-25.5% and 21.0-31.5% of the total weight of non-volatile material of (a) plus (b) plus (c).

  • Patent number: 4400479
    Abstract: A coating composition adapted for repairing a damaged coating on a substrate comprises as the binder a mixture of a polyacrylate, an acrylated alkyd resin and a cellulose ester which form 100 percent of the binder. The coating composition is particularly well suited for use in preparing damaged paint on a motor vehicle body. The binder may be mixed with a volatile inert organic solvent for the binder in making the composition. The composition has a higher solids content than composition usually used for repairing damaged coatings and much thicker layers of the coating composition may be applied. By mixing the components of the binder in the ratio of 10 to 60 parts by weight of polyacrylate to 30 to 75 parts by weight of acrylated alkyd resin and 5 to 45 parts by weight cellulose ester to form the binder a coating composition having reduced tendency to crack and of improved solids content is obtained.

  • Patent number: 4332917
    Abstract: Method for preparing a polymer alloy which is stable and homogeneous up to high temperatures, from component (a) one or more polymers of high molecular weight, having anhydride groups and component (b) one or more polymers of high molecular weight, having groups which have the ability to interact with hydrogen atoms to form hydrogen bonds, wherein first a solution of component (a) is prepared in an organic solvent, to which solution then component (b) is added, whereas component (a) in dissolved state is protolyzed in whole or in part, prior to or after the addition of component (b) under the action of protolyzing agents, whereupon the solvent is removed; together with the formed products obtained from such a polymer alloy, such as granules, fibres, foils, foam, etc.
