Synthesis of Polybutadiene Quaternary Ammonium Salt and Its Intercalation into Montmorillonite
摘要
Abstract
Macromolecule polybutadiene quaternary ammonium salt (HTPB-QAS) was prepared by acid catalytic method using hydroxyl terminated polybutadiene (HTPB),epichlorohydrin and w=33％ trimethylamine solution as starting materials and three boron fluoride ethyl ether complexes as the catalyst.The effects of material ratio,catalyst amount,ring-opening time and temperature,and ring-closing time on the conversion rate of hydroxyl group in HTPB were studied.HTPB-QAS was successfully synthesized with the conversion rate of hydroxyl group of 65.7％ as confirmed by FT-IR and 1H-NMR.By solution method and static method,HTPB-QAS was intercalated into Na-MMT to obtain HTPB and NaMMT nanocomposites (HTPB-OMMT).XRD,SAXS,FT-IR and TEM results showed that HTPB-QAS was successfully inserted into Na-MMT layers,and TGA results showed that the thermal stability of the composites was improved obviously.关键词
