Abstract: The mechanical properties of cured polypropylene carbonate(PPC) /epoxy resin (EP) system were investigated by means of dynamic mechanical analysis and stress-strain curves. The influences of molecular weight and contents of PPC on the properties were also studied. The resuIts showed that the half width of tan3 peak increases with the increase of PPC content. The optimum mechanical properties would be achieved when the contents of PPC reach to 20~30 phr.

Key words: polypropylene carbonate, epoxy resin, IPN, dynamic mechanical property
