摘要：NOVELTY - The present invention discloses one kind of completely biodegradable hydrophobic material and its preparation process. The starch-base biodegradable material is prepared through reaction and extrusion in extruder of the following material: starch, PVA, lactone polymer capable of reacting with hydroxy group, biodegradable polymer, initiator and other assistant. The present invention has the advantages of low cost, high hydrophobicity of the product, simple operation, complete biodegradation of the material to eliminate 'white pollution', etc. The present invention is suitable for continuous production.
