Morphology and Phase Behavior in Poly(n-alkyl methacrylate) and Poly(n-alkyl acrylate)

In this research,we observed PAMA(poly(n-alkyl methacrylate)) and PAA(poly(n-alkyl acrylate)¡^side chain crystalline.We find side chain is longer and crystalize more easily,melting point
is higher.In the result of DSC thermograms,the length of side chain is 6 carbons,we can't find any thermal transition.But the length of side chain is 12¡B18 carbons,we only found Tm.In PLM observation,we only get side chain crystalline's picture,and can't see any liquid crystalline yet.
Although in X-ray's illustrative can find layer structure's diffraction peak,but i think this evidence can't prove the system that is liquid crystalline.It just can be said that the layed structure was formed by side chain crystallization.
