由陰離子聚合，作Living Polymerization，並用環氧乙烯或其他環氧化合物，中斷聚合反應，以獲得不同分子量的高分子型之Styrene-Butadiene-Styrene (SBS，Mw=3300,5200,13000)或Styrene-isoprene-styrene (SIS ，Mw=3300)之醇類所得特殊親油基，利用分子末端之醇基與Isophorone diisocyanate (IPDI)作偶合反應，再引入n-BuO-(CH2CH2O)xH (Mw=2000)親水基反應而合成不同之油溶性高分子型界面活性劑。由合成的高分子型界面活性劑測量其表面性質，並探討分子合成與表面性質之間的關係。再由此驗證其它的油溶性高分子型界面活性劑。
由結果得知當親油基與親水基比例越接近，則其界面張力的效能越好，並以此論點探討含SB、SEBS、MPP、SMA的高分子油溶性界面活性劑而結果也都相當符合。

Living polymerization was proceeded through anion polymerization. Reaction of polymerization was broken down by ethylene oxide or oxiranes to obtain various molecular weight of polymer type of styrene-butadiene-styrene (SBS, Mw=3300, 5200, 13000) or styrene-isoprene-styrene (SIS, Mw=3300), lipophilic functional group of alcohol. Alcohol radical in the end of molecular and isophorone diisocyanate (IPDI) proceeded coupling reaction and led into hydrophilic functional group of n-BuO-(CH2CH2O)xH (Mw=2000) to synthesize a series of oil-soluble polymer type of surfactant. The relation of synthesis of polymers and characteristic of surface would be discussed by measuring characteristics of surface of polymers. Then, the results would verify other oil-soluble surfactants.
The ratio of lipophilic functional groups and hydrophilic functional groups was closer, the effect of interfacial tension would be better. Furthermore, lipophilic polymers containing styrene butadiene (SB), polystyrene-b-poly(ethylene/butylene) (SEBS), polypropylene-g-maleic anhydride (MPP) and styrene maleic anhydride copolymer (SMA) fitted in with the same results and supported this point at issue.
