摘    要:利用生命周期评价方法(Life Cycle Assessment,LCA)讨论了PE、PP、GPPS及PVC 4种高分子材料的环境影响问题.结果表明,材料生产的环境影响不仅与资源消耗有关,而且与其各自的工艺环节有着密切的关系.此外,采用不同的LCA方法得到的4种高分子材料的环境负荷的相对值虽然相差很大,但其不同环境负荷之间的排序基本一致.

关 键 词:高分子材料  生命周期评价  环境影响

Abstract:A life cycle assessment was carried out to discuss the environmental impacts of four types of macromolecular materials: PE, PP, GPPS, PVC. The research indicated that the environment impacts of these materials were not only related to resource consumption, but also with to respective techniques. Several different impact assessment methods were adopted to analyze the environmental impacts of the four types of macromolecular materials. The results showed that the absolute value of environmental load was different with different methods, but the ranking of environment load was almost uniform.
Keywords:macromolecular materials  life cycle analysis (LCA)  environmental impact
