摘要
The present invention relates to a novel polyphosphazene-POSS compound having two novel symmetric polyhedral oligomeric silsesquioxanes and a process for their preparation. The hybrid polyphosphazene-POSS compound according to the present invention has a high thermal stability, does not have melting point and orientation, and can have a homogeneous distribution because of the intermolecular cohesion due to the intermolecular repulsion between the BULKI POSS groups. In addition, when the hybrid polyphosphazene-POSS compound according to the present invention is used in a solid electrolyte of a secondary battery, the free volume is increased and the crystallinity of the polymer electrolyte can be effectively lowered, thereby improving the ionic conductivity, A solid electrolyte of a secondary battery improved in storage stability and a lithium polymer secondary battery employing the solid electrolyte can be provided.
