Description

The dynamic mechanical properties and the morphologies for the binary blends of acrylate rubber (ACM) and chlorinated polypropylene (CPP) with 3,9-bis[1,1-dimethyl-2{β-(3-tert-butyl-4-hydroxy-5-methylphenyl)propionyloxy}ethyl]-2,4,8,10-tetraoxaspiro[5,5]-undecane (AO-80), and their ternary systems were investigated. The AO-80 distribution to each phase of an immiscible ACM/CPP blend was studied in term of a shift in glass-transition temperature. It was found that when the AO-80 content is lower than 30% the AO-80 molecules are preferentially dissolved to an ACM continuous phase, whereas as the AO-80 content increases, a part of AO-80 molecules are incorporated to the blend interfaces, and then to the domains of CPP. In addition, the reduction in the domain size of CPP due to adding AO-80 was also observed. A ternary blend of ACM/CPP (7:3) with AO-80 (35%) showed a novel tan δ peak between two peaks corresponding to ACM and CPP. This peak is attributed to an interfacial layer where a super-molecular network is formed. As a result, a ternary blend of ACM/CPP with AO-80 was found to be a very good damping material.
