✦ Synopsis

The dynamic mechanical properties of an organic hybrid consisting of chlorinated polyethylene (CPE) and N,N-dicyclohexyl-2-benzothiazolyl sulfenamide (DZ) were investigated. All the CPE/DZ hybrids showed a single loss tangent (tan ␦) peak in the mechanical spectra. The peak area under the tan ␦/temperature curves around the mechanical loss peak was examined to characterize the damping properties of the CPE/DZ hybrids. We found that there exists a bending point in the relation between the glass-transition temperature (T g ) and DZ content and that the value of T g is saturated in the higher DZ contents, suggesting that excess DZ molecules show self-aggregation and are reorganized.
