  • Process for treating hydroxyl terminated liquid polymers
    Patent number: 4442039
    Abstract: Hydroxyl terminated liquid polymers that are excessively active in reaction with organic diisocyanates may be deactivated by treating the hydroxyl terminated liquid polymer with phosphoric acid or sulfuric acid prior to reaction with the organic diisocyanate so that the hydroxyl terminated liquid polymer is adjusted to an acid number of at least about 6 but not greater than 12. The treated hydroxyl terminated liquid polymer can be used to prepare polyurethanes having improved low temperature properties flexibility and hydrolytic stability.
    Type: Grant
    Filed: May 6, 1982
    Date of Patent: April 10, 1984
    Assignee: The B. F. Goodrich Company
    Inventors: Walter T. Murphy, Clifford D. Guiley, Jr.
  • Stabilized hydroxyl terminated reactive liquid polymers
    Patent number: 4405817
    Abstract: Shelf stability of hydroxyl terminated liquid polymers is vastly improved by mixing a strong inorganic or organic acid, therewith in order to adjust acid number thereof up to about 12. Amount of the acid used is less than 1% by weight of the liquid polymer.
