摘要：

From the quantitative determination of the polar surface tension parameters of Dextran 150 (DEX) and polythylene glycol 6,000 (PEG), it is shown that both polymers are pronounced monopolar Lewis bases. By means of the theory of short-range (SR) (polar or hydrogen bonding) interactions, and also taking into account the influence of long-range Lifshitz-van der Waals (LW) interactions, it is demonstrated that DEX and PEG, immersed in water, repel each other with a sizable repulsion energy.
