报道了1-辛烯与甲基丙烯酸缩水甘油酯自由基共聚的动力学和共聚物组成的研究。通过1H、13 C、杂原子单量子相干核磁共振（NMR）和红外光谱阐明了所得共聚物的化学结构。1H NMR测量表明，当在共聚反应的初始单体进料中使用90摩尔%的该共聚单体时，获得了32摩尔%的1-辛烯在共聚物链中的最大统计掺入。此外，该共聚单体系统的竞聚率估计使用所获得的实验数据，这是拟合的积分形式的共聚方程，利用非线性最小二乘法。据我们所知，这是第一次报告的竞聚率，这种特定的共聚单体系统。为了评估所获得的材料作为分散剂的潜力，对于具有25摩尔%的1-辛烯组成的共聚物，研究了聚合物浓度对铜纳米粉末在有机溶剂中的分散的影响。
Kinetic and copolymer composition investigations of the free radical copolymerization of 1‐octene with glycidyl methacrylate are reported. The chemical structure of the obtained copolymers is elucidated by1H,13C, heteronuclear single quantum coherence nuclear magnetic resonance (NMR) and infrared spectroscopies.1H NMR measurements indicate that a maximum statistical incorporation of 1‐octene in the copolymer chain of 32 mol% is obtained when 90 mol% of this comonomer is used in the initial monomer feed of the copolymerization reaction. Furthermore, the reactivity ratios of this comonomer system are estimated using the obtained experimental data, which are fitted to the integral form of the copolymerization equation utilizing a nonlinear least squares approach. To the best of knowledge, this is the first report on the reactivity ratios of this specific comonomer system. To evaluate the potential of the obtained materials as dispersants, the effect of the polymer concentration on the dispersion of copper nanopowders in organic solvents is studied for a copolymer with a 1‐octene composition of 25 mol%.
