摘要：

The adsorption behaviour of a poly(oxyethylene)-poly(oxypropylene)-poly(oxyethylene) block copolymer onto highly dispersed silica particles in aqueous medium was studied by surface tension measurements and microcalorimetry. The results indicate the existence of a critical adsorption effect. This effect is discussed in terms of a multi-site adsorption accompanied by a lateral interaction of the copolymer molecules within the adsorption layer.
