Abstract : The Rheovibron oscillatory viscoelastomer has been used to compare the rheological behavior of three composites at low temperature near the glass transition point. All three composites are highly filled materials containing 84-88% solids, NH4ClO4, and Al, in an elastomeric matrix. The main purpose of the measurements is to evaluate the efficiency of two surface-active agents: an aziridine polyester showing better adhesion properties between solid particles and the elastomeric binders than an amine polyester. Mixtures of both polyesters are shown to be even more efficient. The dynamic mechanical properties are qualitatively discussed in relation to the mechanism of actions of both surface-active compounds. (Author)
