摘要
淀粉是地球上产量仅次于纤维素的天然高分子，它来源丰富、可再生、价格低廉，通过改性塑化可用于生产淀粉基塑料。淀粉塑料（TPS)作为可降解塑料中的一个重要品类，已经成功实现产业化生产和应用。淀粉塑料是以淀粉为主要原材料的。以淀粉为基础的生物基塑料一般是改性淀粉与聚烯烃(如PP/PE/PS等)的混合物，它的环保意义在于能够减少石化资源的使用，减少二氧化碳排放，废弃物适合焚烧处理。可以很好的解决石油基塑料所带来的资源匮乏和环境污染问题。

Abstract
Starch is the natural macromolecule with the highest yield only next to cellulose on the earth.It is rich in source,renewable and cheap.Starch plastics(TPS),as an important category of degradable plastics,has been successfully industrialized and applied.Starch plastics mainly take starch as raw material. Starch based biological plastics are generally a mixture of modified starch and polyolefin(such as PP/PE/PS).Its environmental protection significance lies in its ability to reduce the use of petrochemical resources, reduce carbon dioxide emissions, and waste is suitable for incineration. This can well solve the problem of resource shortage and environmental pollution caused by petroleum based plastics.
Key words: thermoplastic starch；turpentine；modification；research；
