A series of PDPS/PDMS copolymers were synthesized through living anionic polymerization withn-butyllithium as an initiator. The changes of thermal property as a function of PDPS content were compared with respect to
different types of monomer sequence using differential scanning calorimetry and thermogravimtery. The results indicated that
the related variations of the thermal propertiesvs. the PDPS content and the monomer sequence provided independent operative control for preparing materials with desired thermal
properties. The thermal stability of these copolymers was dramatically improved with introducing PDPS segment. However, the
degree of these improvement pedended greatly on the monomer sequence in the copolymers.
