The characteristics of a scaffold that is the basic component tissue engineering are considerably influenced by fiber diameter fibrous scaffolds. Since significant effect on properties, many researchers have focused estimating based electrospinning parameters. With similar motivation, in this paper, new and simple closed-form expression, which can help fabricating electrospun poly (ԑ-caprolacto...
Zinc alkyl cations supported by N,N-BIAN-type bidentate ligands were found to be highly active in the immortal ROP of ε-caprolactone to yield narrowly disperse and chain length-controlled poly(ε-caprolactone), whether in solution or bulk polymerization conditions.
Graft poly(ε-caprolactone)s (PCLs) with high graft density were synthesized by using random copolymer poly(ethylene-co-vinyl alcohol) (EVOH) to initiate ring-opening polymerization of ε-caprolactone, with and without cocatalyst Sn(Oct)2. The graft copolymer were characterized by IR, 1H and 13C NMR. The solution property and the crystallization behavior were also investigated.
Low-molecular weight poly(epsilon-caprolactone), polylactides and copolymers of epsilon-caprolactone and lactides were obtained by the polymerization of cyclic esters in the presence of a carnitine/SnOct(2) system. Their structures were proven by means of MALDI-TOF, IR and NMR studies. Effects of temperature, reaction time and carnitine dosage on the polymerization process were examined.
