摘要

AbstractThis paper describes the synthesis, physical properties, and the impact modification of poly(N‐phenylnorbornene dicarboximide) (PNDI). Impact modification is carried out both by physical blending with acrylonitrile‐butadiene rubber (Hycar®) and byin situmetathesis polymerization of the monomer with the rubber. Better success is achieved byin situmetathesis polymerization. A copolymer, poly(N‐phenylnorbornene dicarboximide) ‐co‐poly(norbornene nitrile) containing Hycar rubber (PNDI/PNN/Hycar), is prepared with a good balance of high‐heat impact and flexural properties. The melt viscoelastic behavior of PNDI/PNN/Hycar is evaluated and the energy of activation for viscous flow (Ea) was found to be 42 kcal/mol. © 1993 John Wi
