Patent number: 5371288Abstract: N,N'-Di-(branched alkyl)-alkylenediamine-bis-p-aminobenzamides are useful as chain extenders in the manufacture of polyurethane-urea elastomers. These compositions have remarkably uniform reactivities but can be varied structurally to achieve a range of processibility characteristics by altering the melting points of the chain extenders. The preferred compounds melt in a range of 50.degree. to 175.degree. C. while exhibiting t.sub.5000 reactivities of about four minutes. The combination of processing characteristics, reactivities and physical properties of the elastomer products offers advantages not available in commonly used diamine chain extenders of the prior art.Type: GrantFiled: April 13, 1994Date of Patent: December 6, 1994Assignee: Air Products and Chemicals, Inc.Inventors: Kevin R. Lassila, Jeremiah P. Casey

Patent number: 5091583Abstract: The invention pertains to tertiary amines used as catalysts for the preparation of polyurethane foams prepared via the catalytic reaction of a polyisocyanate with a polyol in the presence of blowing agents, etc. The tertiary amine catalysts are prepared by reacting an olefinic nitrile with aliphatic polyol having at least secondary hydroxyl functionality in a ratio less than stoichiometric for providing cyanoalkylated polyol having residual hydroxyl functionality. The resulting cyanoalkylated polyol then is reacted with a secondary amine under conditions for effective reductive alkylation.The tertiary amine catalysts, because of residual secondary hydroxyl functionality, provide for uniform dispersion within a polyurethane, formulation; they provude for additional or extended pot life in polyurethane formulations at temperature below reaction condition, and they are bound by reaction on cure.Type: GrantFiled: May 9, 1991Date of Patent: February 25, 1992Assignee: Air Products and Chemicals, Inc.Inventors: Jeremiah P.

Patent number: 5034426Abstract: The present invention relates to a process for the production of polyurethanes wherein a tertiary amine functionality is incorporated into the side chain of an aromatic diamine, preferably a diaminobenzamide, to form a catalytic polyurethane chain extender. These chain extenders are polyurethane catalysts that provide adequate cure without residual odor and safety hazards associated with the more traditional tertiary amine catalysts. When reacted with the isocyanate reactive group the non-tertiary amine portion of the chain extender is bound to the polymeric network. Diffusion of the catalyst species from the polyurethane has been prevented, thus negating odor and toxicity as problems. These aromatic diamines provide enhanced polyurethane physical properties.Type: GrantFiled: January 22, 1990Date of Patent: July 23, 1991Assignee: Air Products and Chemicals, Inc.Inventors: Jeremiah P. Casey, Susan M. Clift, Kenneth M. Kem
