摘要：

Thermal gravimetry, differential scanning calorimetry, stress-strain and dynamic mechanical testing were performed for pure epoxy resin and epoxy copolymers. Shrinkage, equal density or expansion was obtained by copolymerizing epoxy resin with various amounts of the expanding monomer norbornene spiro-orthocarbonate (NSOC). The glass-transition temperature, thermal-degradation temperature and fracture strength decreased with the introduction of NSOC, indicating that the effect of chain structure on the physical properties of epoxy copolymer was more than that of volume expansion arising from the ring-opening polymerization of expanding monomer NSOC.
