GRAPHICAL ABSTRACT
ABSTRACT
Low-molecular-weight PA6 (LMW-PA6)/hydrotalcite intercalated nanocomposites were prepared via insitu polymerization in the presence of organo-hydrotalcite with alanine as an initiator at 150°C.The results indicated that alanine in the interlayer gallery of hydrotalcite doesn't change the interlayer distance of hydrotalcite, while it can initiate the polymerization of ε-caprolactam. There exsists γ crystalloid of LMW-PA6 in LMW-PA6/hydrotalcite intercalated nanocomposites. The molecular weight distribution of LMW-PA6 in the intercalated nanocomposites have two peaks and the added amounts of organo-hydrotalcite hardly influence molecular weight of LMW-PA6.
