Influence of the ester block polymerization degree on the structure and properties of ester-ether-amide block terpolymers

Abstract

New multi-block thermoplastic elastomers (TPEEA) were obtained, consisting of a crystalline amide block (domains), an amorphous ether block (continuous phase) and an ester block with a variable degree of polymerization, which acts as a compatibilizer. The presence of large interfacial areas was observed. It was found that ester blocks with a molecular weight <600 g/mol mix with other blocks, modifying the phases that constitute them and stabilizing the micro- and nanophase structure of the entire system. Short ester blocks act as nucleation precursors, and in the hard phase they have plasticizing properties.
