利用均聚物溶液统计热力学中的粘度双参数理论和1mhz绝热压缩率测量，研究了醋酸乙烯-丙烯酸甲酯无规共聚物的稀溶液性质。研究了该共聚物的短程相互作用参数和“混合单元压缩性”与母体均聚物的关系。研究发现，聚合物的“混合单元可压缩性”取决于近程相互作用，而不依赖于远程相互作用。
The dilute solution properties of vinyl acetate–methyl acrylate random copolymers are investigated by the viscometric two-parameter theories in the statistical thermodynamics of homopolymer solution at zero frequency and by the measurement of adiabatic compressibility at 1 MHz. The short-range interaction parameter and “compressibility of mixing unit” for the copolymer are examined in relation with those of the parent homopolymers. It is found that the “compressibility of mixing unit” of polymer depends on the short-range interaction independently of the long-range interaction.
