Abstract

The adsorption enthalpies of block- and statistic copolymers of ethylene oxide (EO) and propylene oxide (PO), and of corresponding homopolymers on silica (Aerosil 200) from CCl4 and H2O are determined by microcalorimetry. With adsorption isotherms measured separately from the concentration difference in the solution fraction of adhered segments, p cal, the binding enthalpies have been deduced. The p cal-values from CCl4 decrease with increasing amount adsorbed, molar mass, EO-fraction and -blocklength. The hydroxyl endgroups of the polymers strongly influence the adsorption enthalpies. With results on preferential adsorption of the EO-segments the dependences are interpreted by conformation models.
