Thermoplastic poly(ester-block-amide) elastomers (PEAs) comprising hard blocks of oligoester (oligo(butylenes terephthalate), PBT) and oligoamide soft segments (reaction product of diamines with dimerized fatty acid (DFA)) were synthesized and analysed. For preparation of oligoamide block diamine like: piperazine, 1,6-hexamethylenediamine, 1,4-cyclohexanediamine and bis-(3-aminopropyl)-polytetrahydrofuran were used as diamine. The copolymers were obtained with changing mass ratio of the both segments and molecular weight of oligoamide soft block. Paper describes the melt flow index of poly(ester-block-amide)s in relation to the contents and structure of the soft oligoamide blocks. Rheological properties were found to depend on kind of used diamine and soft segment content in copolymer.
