Patent number: 6613867Abstract: The present invention is a thermoplastic polyurethane (TPU) or thermoplastic polyurethane/urea (TPUU) comprising structural units of: a) a diisocyanate; b) ethylene glycol, diethylene glycol, or 1,3-propanediol; c) a diol, a diamine, or an amino alcohol different from the one selected in (b) and having a molecular weight of less than 400 Daltons; and (d) ethylene oxide polyol or ethylene oxide-capped propylene oxide polyol. The TPU or TPUU has low temperature flexibility, high moisture vapor transition rates, and is considerably less expensive than state-of-the-art TPUs or TPUUs. The preferred composition is a TPU that is substantially free of phase segregation, and consequently has clarity and tensile strength not known for TPUs prepared using ethylene oxide polyol or ethylene oxide-capped propylene oxide polyol.Type: GrantFiled: December 5, 2001Date of Patent: September 2, 2003Assignee: Dow Global Technologies Inc.Inventors: Mark F.

Patent number: 6569352Abstract: Disclosed are polyester-ether polyols and their use in urethane prepolymers, urethane foams and non-foam urethane coatings, adhesives, sealants and/or elastomers. Methods for producing such polyester-ether polyols are disclosed, along with methods for producing urethane prepolymers. The polyester-ether polyols of the instant invention are preferably the reaction product of phthalic anhydride, diethylene glycol, and propylene oxide. These polyester-ether polyols are useful as either the primary polyol in urethane compositions or in combination with conventional auxiliary polyester- and/or polyether-based polyols. The polyester-ether polyols impart greatly improved solubility and compatibility to mixtures of either polyether and/or polyester polyols. The polyester-ether polyols of the instant invention are desirably of lower viscosity than their precursor intermediate polyester polyols and are generally soluble in either polyester- and/or polyether-based polyols.Type: GrantFiled: October 25, 1999Date of Patent: May 27, 2003Assignee: Stepan CompanyInventors: Douglas K.

Patent number: 6562881Abstract: An alkoxylate adduct of a polyol. The polyol is an amorphous diol having a melting point above about 100° C. The alkoxylate is propylene oxide, butylene oxide, a mixture of propylene oxide and butylene oxide or a mixture of one or both of propylene oxide and butylene oxide with up to 50 mole % of ethylene oxide. The first polyol has an average of from about 1 to about 5 units of alkoxylate per mole of said amorphous diol. The adduct is useful in preparing urethane (meth)acrylate capped resins and compositions thereof. Resins prepared from such adducts have better manufacturing and solubility properties while retaining similar physical properties to resins prepared from the unadducted diol. The adduct may be for instance a propoxylate of hydrogenated bisphenol A having an average of from 1.5 to 3.5 moles of PO per mole of hydrogenated bisphenol A.Type: GrantFiled: May 30, 2001Date of Patent: May 13, 2003Assignee: Henkel Loctite CorporationInventors: Anthony Jacobine, David Glaser
