Synthesis and Characterization of Biodegradable Semi-Interpenetrating Polymer Networks Based on Star-Shaped Copolymers of ɛ-Caprolactone and Lactide
In this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. The polymers were characterized by nuclear magnetic resonance (NMR) spectrometry, fourier transform infrared spectroscopy (F...

متن کاملPorous thin films based on photo-cross-linked star-shaped poly(D,L-lactide)s.
Self-assembly processes and subsequent photo-cross-linking were used to generate cross-linked, ordered microporous structures on the surfaces of well defined four-arm star-shaped poly(D,L-lactide) (PDLLA) thin films. The four-arm star-shaped PDLLAs were synthesized using an ethoxylated pentaerythritol initiator. Solutions of the PDLLAs were cast in a humid environment, and upon solvent evaporat...
متن کاملPlasticization of poly (L-lactide) bioplastic films with poly (propylene glycol)-b-oligo (-caprolactone)
Liquid -caprolactone (CL) oligomers were synthesized by a ring-opening reaction of CL using a propylene glycol (PPG) as the initiator for use as new plasticizers of poly (L-lactide) (PLA) films. PPG-CL oligomers containing two (PPG-2CL) and four (PPG-4CL) units of CL at both PPG end-chains were prepared. The PLA/oligomer blend films were prepared by solution blending before film casting. The t...
