摘要
简介了活性污泥、土壤分解和特定酶、微生物分解等三类生物降解塑料的试验评价方法,以及日、美有关试验评价工作的进展,特别是美国ASTM的有关标准制订工作概况.另外,本文也简单综述了聚乙烯、乙烯基聚合物、聚酯、聚醚、聚氨酯、聚酰胺等聚合物的生物降解性及其影响因素及机理.
Three kinds of test and estimation methods of biodegradable plastics including degradationby active sludge and soil, specific ferment and microbe and the advances in the test and es-timation in Japan and U.S.A. are introduced. The brief introduction on the relevant stan-dards established by ASTM of U. S. A. are given. The biodegradability, the effective factorsand the mechanisms of polyethylene, vinyl polymer, polyester, polyether, polyurethane andpolyamide are reviewed.
