Abstract
The new poly(ester-amide)s were prepared by polycondensation reaction of 1,8-diaminooctane or 1,12-diaminododecane with some diacid chlorides containing preformed ester groups. These polymers were characterized by DSC, polarized light optical microscopy, X-ray diffractions, FTIR and GPC. These polyester-amides show thermotropic liquid crystalline properties and are easily soluble in N-methylpyrrolidinone. The weight average molecular weight is in the range of 2150-3400 and a very closed polydispersity.
