A series of alternating aliphatic poly(amideester)s, derived from dicarboxylic acid and aminoalcohols, were obtained by polycondensation in melt. All poly(amideester)s were characterized by FTIR and H-1/C-13-NMR spectroscopies. The synthesized polymers showed an inherent viscosity ranging from 0.4 to 1.0 dL g(-1). Thermal analysis showed melting points within the range 100-115degreesC and glass transition within the range 30-60degreesC. Decomposition temperatures were more than 200degreesC higher than the corresponding melting temperatures. The polymers can thus be processed from the melt. The processed polymers were partially crystalline with good thermal stability. (C) 2004 Wiley Periodicals, Inc.
