The dynamic mechanical properties and miscibility of an organic hybrid made from chlorinated polyethylene (CPE) and 2, 2’-methyIene-bis-( 4-methyl-6-cyclohexylphenol) ( ZKF ) are mainly discussed in this paper. It is found that ZKF acts as an antiplasticizer in CPE matrix and has good miscibility even with large ratio in CPE /ZKF hybrids. The glass transition temperature of various CPE /ZKF hybrids determined by DSC give a good fit to Wood’s equation. Bifunctional ZKF is supposed to improve the intermolecular force of CPE, and the improvement is developed when the ZKF content increases. On the other hand, the viscoelastic properties are highly improved with the addition of ZKF. TA and tanδ peak values increase when the ZKF content increase in the CPE /ZKF hybrids, the damping capacity has been improved during the glass transition of CPE /ZKF hybrids. In addition, the glass transition temperature shifts to room temperature from the low temperature with the continuous addition of ZKF to CPE.
