Crystallinity of block copolymer controlled by cyclodextrin

Risultato della ricerca: Article

Abstract

We report a differential scanning calorimetry study to investigate the effect of cyclodextrins (CD) on the crystallinity of a copolymer. Tetronics was selected as copolymer with star-like shape formed by four polyethylene oxide flanked by four polypropylene oxide blocks linked to ethylenediamine central group. The use of CD with different cavity size was exploited for a block selective inclusion. A model for supramolecular association was considered for a quantitative description of the enthalpy data. The polymer chain incorporation into the CD cavity generates a loss of crystallinity. The stoichiometry of the CD/copolymer aggregates can be tuned by changing the CD cavity size. The investigated systems represent interesting necklace-like supramolecular structures with tunable crystallinity. © 2018 Akadémiai Kiadó, Budapest, Hungary
