Title Microphase separation in semifluorinated polyesters
Date 31.12.2007
Number 14343
Abstract Temperature-resolved scattering measurements (SAXS and WAXS) combined with other methods giving thermal behaviour information (DSC, Broadband Dielectric Spectroscopy) were used to get detailed information about the structural changes induced by increasing flexibility of polyesters with semifluorinated side chains and an alternating backbone of isophthalic acid and alkane diols. Intra- and intermolecular microphase separation gives rise to a layered structure with alternating sub-layers of semifluorinated side chains and polyester backbones according to the molecular model reported in [1]. This structure is accompanied by hexagonal and cubic structures in low molecular weight SF-polymers.
