Polyester-amides with liquid-crystalline properties

Some new polyester-amides were prepared by polycondensation reaction of 1,8-diaminooctane or 1,12- diaminododecane with diacid chlorides containing preformed ester groups. These polymers were characterized by DSC, polarized light optical microscopy, X-ray diffractions, FTIR and GPC. They show thermotropic liquid crystalline properties and are easily soluble in N-methylpyrrolidinone.

Fluorinated poly(benzoxazole-ester)s

New poly(benzoxazole-ester)s were prepared by polycondensation of bis(o-aminophenol), such as 2,2-bis(3-amino-4-hydroxyphenyl)hexafluoropropane, with diacid chlorides containing ester groups. The soluble polymer precursor resulting from the first step of polycondensation in N-methylpyrrolidinone (NMP) at low temperature was processed into thin flexible films, which were then thermally treated to reach the fully cyclized structure of poly(benzoxazole-ester)s, as observed by infrared spectra.
