Abstract
A method for producing a biologically degradable polyhydroxyalkanoate coating in the form of an elastomeric film, wherein an aqueous dispersion of polyhydroxyalkanoate or a mixture of polyhydroxyalkanoate is prepared and the dispersion is applied to the surface to be coated, after which water is made or allowed to evaporate to obtain a polyhydroxyalkanoate film, the film formation taking place at a temperature lower than the melting point of the polyhydroxyalkanoate, wherein the polyhydroxyalkanoate is a Pseudomonas polyhydroxyalkanoate other than a polymer or copolymer of &bgr;-hydroxyvalerate or &bgr;-hydroxybutyrate, without requiring additional steps to render the film elastomeric.
