Mechanical spectroscopy is used to study the behavior under accelerated aging of surface‐active additives in highly filled composites using a binder based on an hydroxyl‐terminated polybutadiene. First, the mechanical properties of composites containing an amine polyester or an aziridine polyester are compared to those of a composite without any surface‐active agents. It is thus confirmed that the aziridine polyester is a better surface‐active agent than the amine polyester. The improvement in properties from the aziridine polyester is not affected by accelerated aging at 333°K. It was also established that composites with a mixture of both polyesters showed adequate initial mechanical properties and maintained those properties upon accelerated aging. Various hypotheses are proposed to explain the behavior of surface‐active agents.
