POLYESTER-POLYURETHANE COMPOSITES

摘要

The present invention provides polyester-polyurethane composites made by applying a polyurethane matrix including at least one polyether containing both hydroxyl-functionality and unsaturation-functionality to an unsaturation-containing polyester matrix. Adhesion between the polyester matrix and the polyurethane matrix in the inventive composites is promoted b y the polyether containing both hydroxyl-functionality and unsaturation-functionality.
