用负载型TiCl4/MgCl2催化剂催化1-十八烯（1-oct）与对甲基苯乙烯（pMS）共聚合，得到1-oct与pMS的共聚物[P（1-oct-co-pMS）]。再通过反应性基团功能化法，用HBr/H2O2对P（1-oct-co-pMS）中pMS结构单元上的对位甲基进行选择性溴化，接着用改进的Williamson醚化法将端羟基聚乙二醇（PEG-OH）接枝到P（1-oct-co-pMS）主链上，制备了PEG-OH接枝P（1-oct-co-pMS）[P（1-oct-co-pMS）-g-PEG]的两亲性接枝共聚物，实现了聚长链α-烯烃的功能化。以P（1-oct-co-pMS）-g-PEG为分散剂，山梨糖醇酐油酸酯/失水山梨醇单油酸酯聚氧乙烯醚混合物为表面活性剂，采用高剪切乳化机制备了含水乳化柴油（即柴油乳液），用动态光散射法测定柴油乳液的粒径及其分布。结果表明，含有P（1-oct-co-pMS）-g-PEG的柴油乳液稳定性较好，在室温条件下可以稳定6天以上。
