The DSC data indicated that when K-MAH was acceded into
PA6, The glass-translation temperature (Tg) of PA6 increased a
little, but the Tg of K-MAH decreased, the Tg of PA6 and K-MAH
were anear each other, it showed that the two kinds of materials
have a partial compatibility. But the change of PA6 was less than
K-MAH in Tg, it may be caused by several factors, on the one hand,
the PA6-MAH-K copolymer dispersed in the part of amorphous of
PA6, it not only decreased the chroma of amide because there
wasn’t amide in K-MAH, but also increased the distance between
molecules of PA6, the force between molecules decreased, the form
of hydrogen bond became difficult and the rate of hydrogen bond decreased
