| 中文摘要 | the miscibility and phase behavior of polysulfone (psf) and poly(hydroxyether of bisphenol a) (phenoxy) with a series of copoly(ether ether ketone) (copeek), a random copolymer of poly(ether ether ketone) (peek), and phenolphthalein poly(ether ether ketone) (pek-c) was studied using differential scanning calorimetry. a copeek copolymer containing 6 mol % ether ether ketone (eek) repeat units is miscible with psf, whereas copolymers containing 12 mol % eek and more are not. copeek copolymers containing 6 and 12 mol % eek are completely miscible with phenoxy, but those containing 24 mol % eek and more are immiscible with phenoxy. moreover, a copolymer containing 17 mol % eek is partially miscible with phenoxy; the blends show two transitions in the midcomposition region and single transitions at either extreme. two t(g)s were observed for the 50/50 blend of phenoxy with the copolymer containing 17 mol % eek, whereas a single composition-dependent t-g appeared for all the other compositions. an ftir study revealed that there exist hydrogen-bonding interactions between phenoxy and the copolymers. the strengths of the hydrogen-bonding interactions in the blends of the copeek copolymers containing 6 and 12 mol % eek are the same as that in the phenoxy/pek-c blend. however, for the blends of copolymers containing 17, 24, and 28 mol % eek, the hydrogen-bonding interactions become increasingly unfavorable and the self-association of the hydroxyl groups of phenoxy is preferable as the content of eek units in the copolymer increases. the observed miscibility was interpreted qualitatively in terms of the mean-field approach.
