A kind of method and its application of isobide glycidyl ether modified polyalcohol

The invention discloses a kind of method of the commercial polyalcohol of isobide glycidyl ether modified and its application in synthesis of polyurethane foam.Isobide glycidol ether and commodity polymerized polyalcohol are subjected to graft reaction, modified polyols blend is used to prepare polyurethane foam.The polyurethane foam of polyols preparation after isobide glycidyl ether modified improves 8 31%, density reduction by 5 9%, dimensional stability raising 32 60% than the polyurethane foam compression strength of unmodified polyols preparation.
