No full textA telechelic oligomer with OH and groups was prepd. from L,L-lactide (LA) and 1,4-butanediol and then treated with sebacoyl dichloride and then 1,6-hexanediamine to give poly(L,L-lactide)-polyamide copolymers. Properties of the oligomer and polyesteramide were given. The compn. of the latter varied by 25-45 wt.% LA according to the mol. wt. of the oligomer and ratio of reactants. Yields and viscosities were high with mol. wt. of polyamide blocks being 1000-2000

No full textSynthesis and Characterization of Star-shaped Diblock Poly(e-caprolactone)/Poly(oxyethylene) Copolymers
No full textStar shaped hydroxy terminated poly(e-caprolactone)s were condensed with a-methyl-o-(3-carboxypropionyloxy)-poly(ethyleneoxide)s (Mn=550-5000) to afford a series of four-armed PCL-PEO star diblock copolymers. The polymers were characterized by NMR spectroscopy, SEC, DSC and X-ray diffraction techniques
