Chitin-hydroxyl terminated polybutadiene (HTPB) based polyurethane (PU) was prepared and structure of the pre-designed PU was confirmed using FT-IR spectrometer. The FT-IR analysis confirmed that the crosslinking density increased with increasing the chitin contents in the final PU. During the detailed FT-IR study, it was observed that...

One-step Synthesis of PCL-Urethane Networks using a Crosslinking/de-crosslinking Agent

Thermally reversible cross-linked polycaprolactone-urethane (PCL-U) was prepared in one-step procedure. The PCL-U networks were synthesized from a di-isocyanate (4,4′-methylene bis(cyclohexylisocyanate) (HMDI) and hydroxyl bearing macromers and monomers: hydroxy-terminated PCL, glycerol and a di-alcohol Diels-Alder (DA) adduct. This adduct...
