| 摘 要： | 通过氮气和氩气等离子体聚合废植物油(WO)分别得到高黏度聚合油(WPAR和WPN2)。经凝胶渗透色谱(GPC)和1H NMR分析可知，WPAR和WPN2主要由单体的二聚体及分子量更高的齐聚物组成，是在等离子体作用下通过双自由基中间体的链增长聚合和Diels Alder加成反应得到。四球机测试结果表明：WPAR和WPN2的最大无卡咬负荷（PB）分别达到803.6 N和1 254.0 N，超过了同黏度级别矿物油150BS的承载能力。在测试载荷中WPN2的磨斑直径(WSD)均小于WPAR，显示出优良的抗磨性能。与150BS相比，WPN2展现出较好的减摩性能。

| Abstract: | Polymerized oils(WPAR and WPN2) with high viscosity were obtained by argon and nitrogen plasma polymerization of waste vegetable oil(WO). As shown by GPC and 1H NMR analysis, the plasma polymers WPAR and WPN2, which consisted of dimers and higher molecular weight oligomers of WO, were obtained by the chain growth polymerization of the diradical intermediate and Diels Alder addition. The results from the four ball tester demonstrated that the PB values of WPAR and WPN2 reached 803.6 N and 1 254.0 N, respectively, both surpassed the load carrying capacity of mineral oil 150BS with the same viscosity grade. With the same tested loads the wear scar diameters(WSD) of WPN2 were all smaller than those of WPAR, which showed excellent anti wear ability. Compared to mineral oil 150BS, WPN2 showed better friction reducing performance. |
