The effect of catalyst and segmental composition on the crystallization of multiblock polyesters for biomedical applications (in English)

Polimery 2014, No 7-8, 592

Summary

In the present work, segmented thermoplastic elastomers (TPE) containing hard segments of poly(ethylene terephthalate) (PET) and soft segments comprising amorphous fatty acid ester sequences based on dilinoleic acid (DLA) were synthesized. The aim was to obtain transparent materials with high strength and flexibility. Thermal properties of the obtained PET/DLA copolymers were examined using differential scanning calorimetry (DSC). It was found that segmental composition and new type of catalyst used for the synthesis of PET/DLA copolymers has influence on materials transparency.


Key words: thermoplastic elastomers, crystallization, biomedical applications, poly(ethylene terephthalate)
