摘　　要：以丙烯酸和高碳醇为原料,采用固体酸和阳离子交换树脂作为催化剂合成了一系列丙烯酸高碳醇酯,确定了最佳的催化剂及其用量,并简化了精制工艺,在该工艺条件下酯的收率可达85%以上。同时制备了丙烯酸高碳醇酯的聚合物,并对聚合物的降凝性能进行了探讨。A series of higher alcohol acrylates were synthesized from acrylic acid and higher alcohol using solid acid and cation exchange resin as catalyst.The optimum catalyst and its content were obtained,and the purification process was simplified.Under the conditions,the yield of the ester could reach above 85%.In addition,the higher alcohol acrylate polymer was prepared,the pour point depression performance of the polymer was investigated.
