Preparation and study of new poly(phenylquinoxaline-ether-imide)s

New aromatic poly(phenylquinoxaline-ether-imide)s were synthesized by solution polycondensation reaction of aromatic diamines containing preformed phenylquinoxaline groups with two bis(ether-anhydride)s, namely 1,1-bis[p-{3,4-dicarboxyphenoxy)phenyl]cyclohexane dianhydride or 1,1-bis[p-(3,4-dicarboxyphenoxy)phenyl]fluorene dianhydride. All polymers were easily soluble in organic solvents, such as N-methylpyrrolidinone and dimethylacetamide, and even in less polar solvents like pyridine, tetrahydrofuran or chloroform, and gave flexible films by casting of such solutions. They showed high thermal stability, with an initial decomposition temperature above 300°C and a glass transition temperature in the range of 220-271°C. The polymer films exhibited good mechanical properties with tensile strength in the range of 38.5-78.2 MPa, elastic modulus in the range of 2.8-3.1 GPa and elongation to break in the range of 1.5-4.2%. The polymers showed weight- and number-average molecular weights in the range of 12000-23000 g/mol and 6000-11000 g/mol, respectively.

Aromatic poly(phenylquinoxaline-amide)s containing pendant benzamede groups

Aromatic poly(phenylquinoxaline-amide)s containing pendant benzamide groups have been synthesized by solution polycondensation of equimolar amounts of aromatic diamines having phenylquinoxaline units with 5-(4-acetoxybenzamide) isophthaloyl chloride, in N-methylpyrrolidinone (NMP) as a solvent and in the presence of pyridine as acid acceptor. These polymers were characterized by IR spectra, viscosimetry, gel permeation chromatography, differential scanning calorimetry (DSC) and thermogravimetric analyses. These poly(phenylquinoxaline- amide)s show good solubility in polar aprotic solvents such as NMP, dimethylformamide (DMF) and dimethylacetamide (DMA), good thermal stability with initial decomposition temperature above 330°C and glass transition temperature in the range of 220-335°C. Their weight average molecular weights are in the interval of 29000-91000 and the polydispersity is in the range of 1.4 and 2.5.
