Synthesis and Characterization of Novel Hybrid Ladderlike Polysilsesquioxanes Containing Polypropylene Moieties

摘要

Novel ladderlike polysilsesquioxanes containing polypropylene moieties (LPS-PP) were synthesized from LPS having chloromethylphenyl groups (LPS) and polypropylene having hydroxyl groups (PP-OH). LPS-PP was characterized by FT-IR, DSC, SEM, EDX, and TGA. The obtained LPS-PP shows no melting temperature due to the disappearance of melting temperature of PP, indicating the rigidity of Si-O-Si backbone in ladderlike LPS. The char yield of LPS-PP is higher than that of PP-OH because of the silica parts of LPS. This new LPS-PP can be an interesting candidate to fabricate hybrid materials using interactions or compatibility between PP moieties of LPS and various organic polymers.
