Polyhydroxyalkanoate composition and molded article thereof

The invention discloses a polyhydroxyalkanoate composition and a forming body thereof, and relates to the technical field of high polymer materials. The polyhydroxyalkanoate composition comprises a component A, a component B and a component C, wherein the component A is polyhydroxyalkanoate; and a functional component B; wherein the functional component B is selected from at least one of epoxidized soybean oil, polyoxyethylene, polyoxypropylene and a polyoxyethylene-polyoxypropylene block copolymer. And further, a component C, namely a nucleating agent, is also included. Wherein based on 100 parts by weight of the component A, the use amount of the functional component B is 0.1-10 parts by weight, and the use amount of the component C nucleating agent is 0.1-10 parts by weight. According to the invention, the processing efficiency of the polyhydroxyalkanoate resin can be improved, and meanwhile, high elongation can be maintained.
