Chitin based polyurethanes using hydroxyl terminated polybutadiene, Part II: Morphological studies

International Journal of Biological Macromolecules, 2013
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.

Chitin based polyurethanes using hydroxyl terminated polybutadiene. Part I: Molecular engineering

International Journal of Biological Macromolecules, 2013
Chitin based polyurethanes (PUs) using hydroxyl terminated polybutadiene (HTPB) as soft segment were prepared and the structure of the proposed PU was confirmed using FTIR spectrometer. PU prepolymer was prepared using HTPB and toluene-2,4-diisocyanate (TDI), and the chain was extended with different proportions of 1,4-butane diol (BDO) and chitin ...

Characterization of uncured and cured hydroxyl terminated polybutadiene prepolymer

2020
ABSTRACT Hydroxyl terminated polybutadienes < HTPB) are being used for the production of composite solid propel lants. Liquid hydroxyl terminated polybutadiene can be crossl inked with chain extension by the reaction of the terminal hydroxyl groups with the diisocyanate groups of isophorone diisocyanate < IPDI) and yield polyurethanes.
