摘　　要：钯（Ⅱ）ＤＤＤＰ（１，３双二苯基膦丙烷）催化剂可催化ＣＯ／乙烯／丙烯酸丁酯三元共聚）。考察了催化剂浓度、反应时间、溶剂以及丙烯酸丁酯单体用量对共聚反应的影响。实验结果表明，在上述４个因素中，丙烯酸丁酯单体用量对该三元共聚反应的影响相对较大，利用１ＨＮＭＲ、１３ＣＮＭＲ、ＦＴＩＲ以及ＦＴ激光拉曼光谱对产物进行了表征，结果表明，产物中ＣＯ与烯烃（乙烯或丙烯酸丁酯）呈线性交替排列结构，并对其端基作了详细分析。Pd(Ⅱ) DPPP(1,3 bis(diphenylphosphine) propane) catalyst can catalyze the terpolymerization of CO, ethylene and butyl acrylate. The effects of catalyst concentration, reaction time, solvents and the dosage of butyl acrylate to the terpolymerization were investigated. The experimental results show that, among the four factors described above, the dosage of butyl acrylate has strongest effect to the terpolymerization. The products were characterized by 1H NMR, 13 C NMR, FT IR and FT Laser Ramer spectra, which proved the linear alternative structure of CO and olefins(ethylene or butyl acrylate) in the backbone, and the end groups of the product were analyzed.
