新型以二氧化碳共聚物为基质的水性聚氨酯(英文)

A novel carbon dioxide-copolymer based aqueous polyurethane

以二氧化碳和环氧乙烷为原料,在高分子负载双金属氰化物的催化下,通过调节聚合得到了聚碳酸酯多元醇。以该多元醇和异佛尔酮二异氰酸酯为主原料,合成了一系列聚碳酸酯型水性聚氨酯乳液,该多元醇中二氧化碳单元的含量较高,反应能耗低,其生产成本与普通聚醚相当。

Carbon dioxide （ CO2 ） itself has little value by far but contributes much of the greenhouse effect, on the other hand, it is abundant, cheap, nontoxic and inflammable as raw material. In our synthesis process, under the catalysing of the polymer supported bimetallic cyahate catalyst （PBM）, CO2 and ethylene oxide can be copolymerized to produce a diol poly （ethylene ether carbonate） polyol （PEC）,
