摘要

The static and dynamic mechanical properties of full-interpenetrating polymer networks (IPN) based on blocked polyurethane (PU) and vinyl esters (VE) were examined. The dynamic technique was used to determined the damping behavior across a temperature range. The glass transition temperature of IPNs were shifted inwardly compared with pure PU and VE, which indicated that the blocked PU-VE IPNs showed excellent compatibility. The glass transition temperature was shifted to a higher temperature with increased filler content. The dynamic storage modulus of IPNs increased with increasing VE and filler content.
