Polyurethane (PU) is one of the most important plastics in the world plastic industry. Industrial production of PU is generally carried out by bulk or solution polymerization with homogeneous catalysts. Poly(2-diethylamino ethylacrylate) (P(DEAEA)) and poly(2-diethylamino ethylacrylate-co-2-hydroxy ethylmethacrylate) (P(DEAEA-co-HEMA)) gels were synthesized by free radical polymerization. The swelling behavior of the synthesized gels in toluene at 25 °C was examined. Subsequently, the catalytic effects of these catalysts on the synthesis of (PU) by both bulk and solution polymerizations were investigated. Optimum particle diameter and catalyst amount were determined for catalysts used in PU synthesis reaction. Both gels were found to be more effective in the PU synthesis reaction than triethylamine (TEA), which is currently used commercially. In addition, it was found that the gels retained 95% of their efficiency, despite being reused 30 times in the PU synthesis reaction. Finally, the kinetics of PU synthesis reactions with catalysts were studied.

聚氨酯（PU）是世界塑料工业中最重要的塑料之一。PU的工业生产通常通过本体催化剂或溶液均质催化剂进行。聚（2-二乙基氨基乙基丙烯酸酯）（P（DEAEA））和聚（2-二乙基氨基ethylacrylate-共-2-羟基乙酯）（P（DEAEA-共-HEMA））凝胶是通过自由基聚合合成的。在25℃下检查了合成凝胶在甲苯中的溶胀行为。随后，研究了这些催化剂对本体聚合和溶液聚合合成（PU）的催化作用。确定用于PU合成反应的催化剂的最佳粒径和催化剂量。发现两种凝胶都比目前商业上使用的三乙胺（TEA）在PU合成反应中更有效。另外，发现凝胶尽管在PU合成反应中重复使用了30次，但仍保留了其效率的95％。最后，研究了用催化剂进行聚氨酯合成反应的动力学。
