聚丙烯酸酯是一类具有优良性能和广泛用途的高分子材料。为了探讨材料性能与分子结构的关系,我们用小角激光光散射法、膜渗透压法、稀溶液粘度法及高效体积排斥色谱法研究了聚丙烯酸丁酯的(PBA)稀溶液性质。订定了聚丙烯酸丁酯在四氢呋喃中的极限粘数-分子量关系式。估算了分子的无扰尺寸与热力学参数。证明该聚合物与聚苯乙烯在所用的色谱条件下符合流体力学体积普适标定关系。
Polyacrylate is a class of high performance polymer materials and a wide range of uses. In order to investigate the relationship between material properties and molecular structure, we studied the properties of dilute poly (butyl acrylate) (PBA) solution using small-angle laser light scattering, membrane osmometry, dilute solution viscosity and high performance exclusion chromatography. Set the polybutyl acrylate in tetrahydrofuran in the limit viscosity - molecular weight relationship. The unscaled size and thermodynamic parameters of the molecule are estimated. It is proved that the polymer and polystyrene meet the standard calibration of hydrodynamic volume under the chromatographic conditions used.
