New aromatic polyesteramides: synthesis and properties (in English)

Polimery 2011, No 4, 263


DOI: dx.doi.org/10.14314/polimery.2011.263


Summary

New aromatic polyesteramides with fairly high average molecular weight [(72—229) · 103] and rather narrow polydispersity in the range of 2.0—3.7 were prepared by polycondensation reaction of different aromatic diamines with a diacid chloride containing preformed ester groups. These polymers, easily soluble in N-methylpyrrolidinone, were cast into transparent, flexible films of various thickness (5—40 µm). The polymers showed high thermal stability with initial decomposition temperature above 340 °C and glass transition temperature in the range of 190—220 °C. The viscoelastic behavior of the new polyesteramides was investigated in the temperature range from -100 °C to 260 °C by dynamic mechanical analysis.


Key words: polyesteramides, synthesis, chemical structure, thermal stability, viscoelastic properties
