| Abstract: |
| The influence of the homogenizing agent HA2 on the surface tension，functional group and boundary layer of NR/CIIR(30/70)blend was studied by using contact angle tester，FTIR，SC and TEM.An action mechanism of HA2 was proposed that the homogenizing agent HA2 consisting of various substances with different polarities acted as a physical or chemical “bridge” on the boundary layer between two rubber phases to accelerate the penetration and diffusion of two phases to each other；the resin component in HA2 was in the glass state at low temperature and had reinforcing effect on rubbers，but it was in the viscous flow state at processing temperature and had lubricating effect on rubbers because it had a higher flow ability than those of rubbers and could decrease the friction between rubbers. |
