  • Isocyanate functional polymers
    Patent number: 5098788
    Abstract: Isocyanate functional polymers useful as crosslinking agents or as moisture curing polymers, which comprise the addition polymerization reaction product of:(a) 1 to 100% by weight of at least one isocyanate functional ethylenically unsaturated monomer which comprises the reaction product obtained by the gradual addition of an ethylenically unsaturated monomer having a single active hydrogen to a diisocyanate selected from the group consisting of isophorone diisocyanate and 2,4 toluene diisocyanate wherein the final molar ratio of active hydrogen containing monomer to diisocyanate is essentially 1 to 1; and(b) 0 to 99% by weight of at least one ethylenically unsaturated monomer which is free of active hydrogen functionality and which is copolymerizable with the ethylenically unsaturated isocyanate functional monomer.
    Type: Grant
    Filed: December 26, 1990
    Date of Patent: March 24, 1992
    Assignee: The Sherwin-Williams Company
    Inventors: Brian C. Petrie, Thomas W. Druetzler, Rodney M. Harris
