摘　　要：合成了一系列丙烯酰胺－丙烯酸甲酯共聚物铑配合物，采用Ｘ－射线光电子能谱（ＸＰＳ）和ＩＲ光谱研究了其中存在的配位结构．通过催化甲醇羰基化反应制备乙酸，考察了它们作为该反应的催化剂的性能，并证明了该催化剂体系具有高活性。A series of acrylamidemethylacrylate copolymer rhodium complexes were synthesized. By using Xray photoelectron spectrum and IR spectrum, the coordination units in the complexes were studied. Their catalytic properties in carbonylation of methanol to acetic acid was also examined. Experimental results reveal that these complexes have high catalytic activity with high selectivity and low erosion in carbonylation of methanol.
