摘要：
The dynamic mechanical properties of polyurethane (PU) grafted epoxy polymer networks have been investigated. The glass transition region is successfully broadened on variation of the degree of phase separation. The tensile strength initially increases with increasing PU content and reaches its maximum value when the PU/epoxy ratio is about 20/80.
