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.
La présente invention concerne une composition de mélanges à base de polymère de poly(hydroxybutyrate) et d'huiles végétales, servant à préparer un polyester de polyol biodégradable. Dans le procédé, le poly(hydroxybutyrate) et l'huile végétale réagissent à la chaleur et produisent le polyester de polyol qui, une fois purifié, peut être utilisé dans des applications analogues à des applications du polyuréthane classique: adhésifs, mousses, élastomères et peintures.
