| Abstract: | A thermal reversible crosslinking agent cyclopentadienyl sodium(CPDNa) was prepared and then reacted with chlorinated polyethylene(CPE),thus a thermal reversible crosslinking CPE rubber was prepared.The influence of quantity of CPDNa on the replacement ratio of chlorine atoms,the crosslinking degree of CPE rubber and the gelling time of crosslinking reaction was studied respective-ly.The structure and thermal performance of the product were characterized by FTIR and DSC. |
