| 摘 要： | <正> 聚甲基丙烯酸己磺酸钠(PSSHMA)是我们最近合成的,具有较好的抗凝血性能。对于带磺酸基聚合物抗凝血性能的研究,文献报道还不多。我们用羟基己磺酸钠与甲基丙烯酸反应制备了甲基丙烯酸己磺酸钠(SSHMA)新单体,在此异相酯化反应中,使用了四丁基硫酸氢铵(TBAB)作为催化剂,使反应较顺利的进行,得纯单体。经复钙时

| Abstract: | The sodium salt of poly-6-sulfohexyl methacrylate (PSSHMA) has been synthesized. In 0.15M NaCl, refractionation and triangle fractionation by precipitation from a solvent-nonsolvent mixture was carried out by adding alcohol to a dilute aqueous solution of the PSSHMA. Mw and η] were measured by means of KMX-6 small angle laser light scattering spectroscopy and viscometry. Empirical correlation between intrinsic viscosity and molecular weight was obtained as follows η] - 1.80×10-2 M0.68 The selection of fractionation condition for aqueous solution of PSSHMA polyelectrolyte and reasonable condition of measurement of light scattering and viscometry were also discussed. |
