Abstract
The effect of polychlorodiphenyl (a low-molecular plasticizer) on the dynamic mechanical characteristics of epoxide polymers, namely, their strength, creep, and water absorption, are studied over a wide temperature range. Modification with polychlorodiphenyl is found to increase the rigidity and decrease the molecular-group mobility of a polymer, which correlates with changes in the physicomechanical properties. The effect of polychlorodiphenyl, different than that of other plasticizers, is explained here by a closer intermolecular coupling and a smaller free volume within the system, as has been confirmed by results of infrared spectrometry, as well as by measurements of density and sorptive properties.
