我们报告的第一个例子交替共聚的极性乙烯基单体和一氧化碳使用醋酸乙烯酯。采用钯催化剂与膦磺酸盐双齿配体制备具有高分子量的交替共聚物。NMR和MALDI-TOF MS分析表明，所得材料是乙酸乙烯酯和一氧化碳的交替共聚物。这也是第一个非自由基途径的聚合物合成与醋酸乙烯酯，一个最便宜和容易获得的极性乙烯基单体，作为一个主要组成部分。
We report the first example of alternating copolymerization of a polar vinyl monomer and carbon monoxide using vinyl acetate. Alternating copolymers with high molecular weights were prepared employing palladium catalysts with phosphine-sulfonate bidentate ligands. NMR and MALDI-TOF MS analyses revealed that the obtained materials were alternating copolymers of vinyl acetate and carbon monoxide. This is also the first nonradical pathway for polymer synthesis with vinyl acetate, one of the most inexpensive and readily available polar vinyl monomer, as a major component.
