Abstract: In this paper, the environmental impact of each life cycle stage of carbon dioxide－based biodegradable polymers is studied. It shows polymers production is the key stage. Especially, global warming, acidification, toxicity to human health and depletion of non-renewable resource are the main factors of environmental burden.

摘要： 对以部分石油路线生产的二氧化碳基聚合物生命周期各阶段的环境协调性进行了研究。研究发现，聚合物生产阶段的环境负荷是影响其整个生命周期环境负荷的关键阶段，而温室效应、酸化效应、人体毒害效应以及不可再生资源消耗等分类环境影响是影响聚合物生产阶段环境负荷的主要因素。
