Resum
Poly(butylene azelate-co-butylene succinate) samples with different azelate/succinate ratios were synthesized and characterized. Calorimetric data indicate a semicrystalline character for all copolyesters studied and a melting point depression that could be interpreted on the basis of complete exclusion of comonomers from well organized lamellae. Crystallization first occurred through the succinate rich segments, which resulted in a peculiar behavior of copolymers having an intermediate composit...
