The proposed friction reducing mechanism of high molecular weight additives that might be brought by the high adsorption capability or low desorption tendency of molecules was confirmed experimentally. It was also found from the temperature programmed experiments that although the low molecular weight compounds having long straight alkyl chain exhibited better lubrication performance under moderate temperature, the high molecular weight compounds showed excellent lubrication performance under higher temperature. It was confirmed from the various experiments using polar base oils that the improvement of lubrication performance of high molecular weight additives is related to the swelling of long molecular chain.

实验证实了高分子量添加剂的减摩机理可能是由于分子的高吸附能力或低脱附倾向所致。程序升温实验还发现，虽然具有长直链的低分子化合物在中温下具有较好的润滑性能，但在较高温度下具有良好的润滑性能。通过使用极性基础油的各种实验，证实了高分子量添加剂润滑性能的改善与长分子链的溶胀有关。
