Water is utilized to prepare self-blown non-isocyanate polyurethane foams by in situ generating the blowing agent (CO2) during the polymer network formation. The partial hydrolysis of one of the comonomers, the cyclic carbonate, generates the blowing agent. The process is facile, versatile, up scalable, uses low cost readily available reagents, can be complete in 30 minutes and is compatible with existing
通过在聚合物网络形成过程中原位产生发泡剂 (CO 2 ),水被用来制备自发泡非异氰酸酯聚氨酯泡沫。其中一种共聚单体环状碳酸酯的部分水解会产生发泡剂。该过程简单、通用、可扩展,使用低成本、现成的试剂,可在 30 分钟内完成,并与现有的聚合物发泡基础设施兼容。
