  • Method of producing polyurethanes with increased resistance to abrasion
    Patent number: 4206102
    Abstract: Abrasion resistant polyurethane elastomers using a combination of a waxing agent, a powdered mineral type lubricant and a polyhalogenated polyalkylene powder are disclosed. Although all three types are known to impart abrasion resistance to polyurethane elastomers, a synergistic effect has been found in the use of these additives such that better abrasion resistance is found with smaller quantities of additives.
    Type: Grant

  • Molecular weight control of polyurethane elastomers
    Patent number: 4071505
    Abstract: Polyurethane elastomers are prepared by reacting organic polyisocyanates with organic polyhydroxyl compounds and a mono-functional secondary hydroxyl group containing chain terminator. The chain terminator can be added to the polyhydroxyl compound prior to the reaction with the polyisocyanate.
