摘　　要： 合成了不同聚合度的松香季戊四醇酯聚氧乙烯醚 (RPEO)。测定了产物的表面物理化学性能 :表面张力 (δ) (34.4～ 4 0 .5 )× 10 -5N/cm ,临界胶束浓度 (CMC) 2 6～ 6 5mmol/L ,钙皂分散指数 (LSDP) 4 .2 %～ 17.5 % ,对松节油乳化力 (EP) 5 8～ 184s ,浊点 (CP) 38～ 75℃。研究了环氧乙烷 (EO)聚合度 (n)对产品表面物理化学性能的影响 ,随着n的增加 ,δ先下降 ,然后逐渐上升 ,CMC、钙皂分散力、CP、EP逐渐升高。 A series of rosin pentaerythritol ester polyoxylethylene ether (RPEO) with different polymerization degree (n) of epoxy ethane (EO) were synthesized. Surface physicochemical properties of these products were measured. The results showed that surface tension (δ) varied from 34.4×10^(-5) to 40.5×10^(-5) (N/cm), critical micelle concentration (CMC) from 26-65(mmoL/L), lime soap dispersing power (LSDP) from 4.2 % to 17.5 %, emulsifying power (EP, with turpentine) from 58 s to 184 s, cloud point from 38 ℃ to 75 ℃. The (relations) between surface physicochemical properties of the products and polymerization degree of EO were first studied systematically. With the increase of n of EO, the surface activity was increased firstly, then (towards) stable or dropped a little, the application properties, such as EP, CP and LSDP, were improved with increasing of n, and reached balance where n equaled to 10.
