| Abstract: |
| The structure and dynamic properties of hindered phenol AO-60/IIR composite were investigated.The results showed that,IIR phase was continuous phase and hindered phenol AO-60 phase was dispersed phase in the composite.Super molecular network structure was formed by hydrogen bonding among AO-60/molecules,and between AO-60 molecule and other polar groups in the crosslinked IIR matrix.As the addition level of AO-60 increased,the tanδ peak of IIR vulcanizates moved to higher temperature zone,but started to move back to low temperature when the addition le-vel exceeded 30 phr.The storage modulus of IIR vulcanizate in the temperature range of -35～-10 ℃ increased as the addition level of AO-60 increased. |
