Abstract：The processabilities and rheological behaviour of trans- 1, 4- polyisoprene(TPI) were studied. The results showed that TPI had good processabilities and was fit for milling, internal mixing and extruding. The rheological behaviour of TPI was in accordance with the equation r = K γn. The viscous flow activation energy of TPI was about 20 ～ 28k J/mol.
