| 摘 要： | 采用滴体积法及Wilhelmy动态接触角测定法测定了丙烯酸双环戌烯基酯 (DCPA)、丙烯酸三环戌烯基酯 (TCPA)、丙烯酸异冰片酯 (IBA)、甲基丙烯酸正丁酯 (BMA)与其均聚物 ,以及氯化聚丙烯 (C1PP)与聚苯乙烯 (PSt)的表面张力及其色散分量与极性分量 ;分别测定了水与CH2 I2 对聚合物PDCPA、PTCPA、PIBA、PBMA、C1PP与PSt表面的动态接触角。以及DCPA、IBA与BMA分别对PSt表面的动态接触角。水、CH2 I2 与PSt为参比物 ,它们的表面张力及其色散分量与极性分量为已知的。从这些数据中得到一些规律性现象 ,并进行了解释。

| Abstract: | By drop volume method and Wilhelmy dynamic contact angle(DCA)method,surface tensions with dispersive and polar components of dicyclopentenyl acrylate (DCPA),tricyclopentenyl acrylate(TCPA),isobornyl acrylate (IBA), n-butyl methacrylate(BMA)and their homopolymers,chlorinated polypropylene(CIPP) and polystyrene(PST) were determined separately,dynamic contact angles of H 2O and CH212 to surfaces of PDCPA, PTCPA, PBMA, CIPP and PSt separately,and dynamic contact angles of DCPA,IBA and BMA separately to the surface of PSt were determined.H 2O,CH212 and PSt were used as reference compounds,their surface tensions with dispersive and polar components had been known.Some regular phenomena were obtained and explained from these data. |
