【摘要】 热固性树脂多为碳杂原子键交联的三维网状分子,在环境与资源问题日益突出的今天,高效经济绿色地将其降解为可重复利用的小分子化合物,具有重要的社会和经济意义。我们课题组针对不同高分子的结构特点,设计了系列高效溶剂及催化剂体系,在近临界条件下,将环氧树脂、不饱和聚酯树脂和交联聚氨酯等热固性树脂的部分化学键催化活化并选择性断裂,将其定向转化为高附加值小分子化合物,为高分子聚合物固体废弃物的资源化利用提供了解决方案。更多还原

【Abstract】 Thermoset resins are mainly composed of three dimension net-like molecules crossliked by C-X bonds.With the increasingly severe environmental and resource problems,efficient,green and economical degradation of the thermoset resins towards small molecule compounds,is undoubtedly of great significance.Based on different polymer structure characteristics,our research team designed several efficient solvent and catalyst systems,which are effective in the decomposing epoxy resin,unsaturated polyester resin and crosslinking polyurethane and conversing them into high value-added small molecule compounds..The progress made this aspect,is potential in polymer solid wastes recycling.更多还原
