Microheterogeneous Polyetherhydroxylurethane Elastomers with Controlled Phase Structure for Structural Adhesives

详细

Polyetherhydroxylurethane elastomers were prepared from mixtures of epoxy urethane oligomers and diglycidyl urethane, synthesized using isophorone diisocyanate, and the properties of the products obtained were studied. Calorimetric and optical microscopic studies proved the heterogeneity of the materials obtained. These materials surpass in the strength and adhesion characteristics the analogs synthesized using toluene-2,4-diisocyanate.
