  • Patent number: 6780932
    Abstract: Disclosed is a process for preparation of final graft polyols via a continuous process. In, addition, a final graft polyol formed by the process is disclosed. The process includes the steps of reacting a plurality of ethylenically unsaturated monomers and a reaction moderator with a macromer having induced unsaturation in the presence of a carrier polyol, a free radical polymerization initiator, and a first graft polyol. The process provides for the preparation of a final graft polyol having a solids level of from 30 to 70% in a continuous process. The final graft polyol produced by the process has a lower viscosity over a range of solids levels, a reduced amount of very large irregularly shaped particles, a reduced viscosity change in response to a change in reaction temperature compared to a typical graft polyol, a reduced tendency to foul the continuous reactor, and a broader particle size distribution compared to an identical graft polyol prepared by a semi-batch process.

  • Patent number: 5601878
    Abstract: The invention relates to a process for the production of two-coat finishes, in which a pigmented basecoat is first applied, the resulting basecoat film is coated with a powder clearcoat, and basecoat and clearcoat are subsequently baked together. In accordance with the invention, the powder clearcoat employed is a powder coating which contains an epoxide group-containing polyacrylate resin as binder and a mixture of (A) a polyanhydride and (B) a carboxyl group-containing polyester resin as crosslinking agent. The polyester resin can be prepared by reacting a diol (b1), a compound (b2) which contains per molecule at least three functional groups selected from hydroxyl, primary amino, secondary amino, carboxyl and acid anhydride groups, and (b3) a dicarboxylic acid in a molar ratio of (b1): (b2): (b3)=0.0 to 3.0: 1.0: 1.5 to 9.0 to give a polyester resin having an acid value of 40 to 300.

  • Patent number: 5532053
    Abstract: The present invention relates to a laminate film useful as a material from which to manufacture surgical and other protective garments. The laminate film comprises at least one layer formed from a first polyetherester copolymer produced from the condensation reaction of dimethyl-1,4-cyclo hexane dicarboxylate and 1,4-cyclo hexane dimethanol and poly(tetramethylene ether glycol) and a second layer comprising a material selected from the group consisting of an ethylene-vinyl acetate copolymer, an ethylene methacrylate copolymer, a second polyetherester copolymer, an anhydride modified polyolefin copolymer, and a polyether block amide copolymer. The total amount of the first polyetherester copolymer present in the laminate is greater than or equal to 35 wt. % of the total weight of the laminate film to provide strength to the laminate film. The laminate film may be bonded to one or more layers of polyesters, polyolefins, polyamides, and non-woven fabrics.
