Preparation of polyurethane substances using specific stabilizer systems |
| abstract |
PURPOSE: To provide a method for preparation of polyurethane substances using specific stabilizer systems. n CONSTITUTION: The polyurethane substances are obtd. by reacting isocyanates (e.g. a mixture of tolylene-2,4- and -2,6-diisocyanates) and bifunctional polyether polyols with the prim. hydroxyl groups in the presence of diazabicyclooctane (an amine catalyst), tin octoate (a catalyst) and a mixture of stabilizers [e.g. a mixture of 2,4-bis(n-octylthiomethyl)-6-methylphenol and an industrial mixture obtd. by reaction of diphenylamine with diisobutylene]. Oxidative resistance of polyurethane substance is remarkably improved. n COPYRIGHT: (C)1992,JPO |
