  • Polyether based urethanes with superior dynamic properties
    Patent number: 4182825
    Abstract: Hydroxy terminated polyethers are capped with toluene diisocyanate, and the amount of unreacted toluene diisocyanate substantially reduced. When cured with 4,4'-methylene-bis-(2-chloroaniline), the cured products have superior dynamic properties to the corresponding toluene diisocyanate capped polyethers with usual unreacted toluene diisocyanate content. The cured products are useful in fabricating industrial tires.
