摘　　要：以玉米淀粉为原料,以醋酸酐为乙酰化试剂,氢氧化钠为催化剂,利用微波辐射技术制得乙酰化淀粉。用制备的乙酰化淀粉与聚丁二酸丁二醇酯(PBS)共混,制备了可生物降解热塑性淀粉塑料。研究了共混物制备的最佳工艺条件及其力学性能、生物降解性能及吸水性能,并对产物进行了红外光谱结构分析和表面电镜扫描分析。With corn starch as raw materials and acetic anhydride as acetylation agent, sodium hydroxide as catalyst, the use of microwave radiation technology obtained acetylated starch. With the preparation of acetylated starch and poly butylene succinate （PBS） blends were prepared by thermoplastic starch biodegradable plastics. Blends studied the optimum conditions of preparation and mechanical properties, bio-degradable properties and water absorption, and infrared spectra of products were structural analysis and surface scanning electron microscope.
