Abstract
Viscoelastic properties of an organic hybrid of chlorinated polyethylene (CPE) and N,Ndicyclohexyl-benzthiazyl-2-sulfenaamid (DZ) are investigated. All CPE/DZ hybrids show a single loss tangent (Fan δ ) peak. Its position shift linearly to higher temperature and its maximum value increases nonlinearly with increasing DZ content. The energy absorptinity (EA, a ratio of loss modulus to complex modulus) is used to characterize these hybrids. The DZ content dependence of EA changes at a critical value. The existence of a bending point in the DZ content dependence of glass transition temperature and energy absorptinity is due to the microseparation and the crystallization of DZ molecules in CPE/DZ hybrids with high DZ content. The molecular structural model can successfully explain the influence of dispersion state of DZ molecules in the matrix polymer CPE on the maximum value and the position of Tan δ of CPE/DZ hybrids.关键词
