The present invention refers to a composition of mixtures based on poly(hydroxybutyrate) polymer and vegetable oils, with the object of preparing a degradable polyol polyester. In the process, the poly(hydroxybutyrate) plus the vegetable oil react under heating, producing the polyol polyester, which once purified can be utilized in applications similar to those of the traditional polyurethane: adhesives, foams, elastomers and paints. |
