| Abstract: |
| The thermoplastic dynamic vulcanized elastomer（TPV） was prepared by blending high-density polyethylene（HDPE） with chlorosulfonated polyethylene（CSM），and high-density polyethylene grafted maleic anhydride（HDPE-g-MAH） was used as a compatibilizer to improve the compatibility between HDPE and CSM.The effect of HDPE/CSM blending ratio and HDPE-g-MAH amount on the properties of TPV was investigated.The results showed that with the increase of CSM amount，the mechanical property of TPV decreased first and then increased，the glass transition temperature（Tg） increased，and the flame retardant property was improved.After adding HDPE-g-MAH，the mechanical property of TPV improved，the Tg decreased，the compatibility between HDPE and CSM was better，the CSM particles dispersed more evenly in the system，and the tensile section of TPV was smoother. |
