Publication number: 20030176617Abstract: Disclosed are certain moisture curable prepolymers formed by the reaction of diphenylmethane diisocyanate (MDI) with conventional polyether polyols to produce sealants and coatings exhibiting excellent combinations of physical properties, most notably, high tensile strength, high tear resistance, and high elongation. These combinations of physical properties in the moisture-cured polymer are superior to those obtained from prepolymers of the so-called “low unsaturation” polyether polyols. The moisture curable prepolymers offer improved polymer properties, reduced viscosity, and lower raw materials cost in relation to the prior art prepolymers based on low unsaturation polyether polyols.Type: ApplicationFiled: April 16, 2003Publication date: September 18, 2003Inventor: Chin-Chang Shen

Patent number: 5962619Abstract: A process for making clear elastomers is disclosed. First, a polyol having a narrow molecular weight distribution (Mw/Mn<1.5) reacts an aromatic diisocyanate at an NCO/OH ratio from about 1.3 to about 3.0 to give a non-viscous isocyanate-terminated prepolymer. A mixture that contains this prepolymer and an aliphatic diisocyanate is then reacted with an aromatic diamine to give a clear elastomer. The elastomers have excellent overall physical and mechanical properties, including resilience greater than 55%. The elastomers are valuable for in-line skates and other applications for which clarity is important.Type: GrantFiled: March 16, 1998Date of Patent: October 5, 1999Assignee: ARCO Chemical Technology, L.P.Inventors: Stephen D. Seneker, Chin-Chang Shen
