| The effect of brominated p-tert-octyl phenolic-formadehyde curing resin(201 resin) on the dynamic mechanical properties of IIR was investigated.The results showed that,as the addition level of 201 resin increased,the tanδ peaks of IIR vulcanizates shifted to higher temperature zone,and the maximum value of tanδ tended to decrease;at low temperature,the storage modulus（E′） of IIR vulcanizate decreased gradually;however,at high temperature range,theE′increased gradually,and the platform of loss modulus elevated gradually. |
