Resumen:
Poly[N-(2-hydroxyethyl)-â-propylamide] oligomer is synthesized using a simple enzymatic procedure involving Candida
antarctica lipase B. This novel compound is obtained by a green and chemoselective method from economic reactants in good
yield. The â-peptoid oligomer is characterized by spectroscopic methods showing low molecular weight and low dispersity.
Two derivatives of the â-peptoid oligomer are prepared by acetylation and by grafting polycaprolactone by ring opening
polymerization from the pendant hydroxyl groups. These products are blendedwith polycaprolactone to make films by solvent
casting. The inclusion of the acyl derivatives of the â-peptoid to polycaprolactone affects the morphology of the film yielding
microstructured and nanostructured patterns.
