The present invention relates to compositions of mixtures based on vegetable oils and poly (hydroxybutyrate) polymers for the purpose of producing degradable polyol polyesters. In the process, the poly (hydroxybutyrate) and vegetable oil are reacted under heating to produce a polyol polyester, which once purified is an application similar to that of traditional polyurethanes, such as adhesives, foams, elastomers and paints It can be used to. |
