Towards polymer-inorganic hybrid molecular composites: Calorimetric studies of the polymer-inorganic particles interaction

Abstract

Inorganic particles of 3 CaO · SiO2 were reacted in water dispersion with dihydrophilic ionic-nonionic block copolymers, and the heat effect of interaction was measured by calorimetry. The ionic block was constituted of monoesters of phosphoric acid or alkyl phosphonic acid, both built on the polyglycidol block, attached to the poly(ethylene oxide) block. The heat evolved during the interaction is a function of the degree of phosphorylation (phosphonylation). The higher the degree of -OH substitution the stronger the interaction, the latter being stronger for phosphates than for phosphonates.
