摘要
目前国外有三类重要的生物降解塑料,第一类是以天然高聚物为基的,第二类是以天然单体合成的高聚物为基的,第三类是以发酵过程生产的高聚物为基的。第一类已有大量论文报道,本文只综述第二类及第三类生物降解塑料的制造、特点、应用及发展现状和前景。
There exits three types of bioplastics：（1） based on polymers directly form matural origins;（2） based on polymers polymerized form matural monomers;（3） based on polymers produced via fermentation processes.In this paper,the performances,characteristics,applications and development trends of three types of bioplastics are summarized and discussed.
