A super-tough polycarbonate (PC) blend was obtained by using epoxidized ethylene propylene diene (eEPDM) rubber as modifier. The notched Izod impact strength of PC/eEPDM (96/4) blend shows a great improvement, with a value about 25 times of that of pure PC. Finely and homogeneously dispersed rubber particles (0.2-0.8 μm) in the PC matrix indicated good adhesion between the eEPDM rubber phase and...
In this paper, unepoxidized ethylene propylene diene rubber (uEPDM) was first epoxidized with formic acid and H 2 O 2 , and then the epoxidized ethylene propylene diene rubber (eEPDM) was melt-mixed with PBT resin in a Brabender-like apparatus. Toughening of PBT matrix was achieved by this method. The dispersion of rubber particles and phase structure of the blends were also observed...
