Preparation of fibers from terpoly(ester-ether-ester)s by melt spinning or electrospinning from the solution

P. Zdebiak

Abstract

Novel terpoly(ester-ether-ester)s (TEEE) built of hard segments, formed by poly(butylene terephthalate) (PBT), and soft blocks built of dilinoleic acid (DLA) residues and poly(ethylene glycol) (PEG) of different molecular weights (Table 1) were prepared. The fibers were prepared from the materials obtained using the methods of melt spinning or electrospinning from the solution (Fig. 1 and 5). The effects of PEG molecular weight and addition of organic thermal stabilizer (alfa-tocopherol, VE) as well as of addition of inorganic modifier (hydroxyapatite, HAP) on melt flow rate (MFR) (Fig. 2) and on mechanical (Fig. 3) and fiber-forming properties of TEEE were studied. Hybrid microfibers were prepared by melt spinning from the system containing HAP nanocrystalline ceramics. It was found that this ceramics thermally stabilized the material similarly as VE did. Terpolymers prepared from PEG of higher molecular weight (PEG4600) showed very good mechanical properties and fibers prepared exhibited excellent elastic properties (high values of elastic recovery, Table 2).
