Functionality distribution and crosslink density of hydroxyl‐terminated polybutadiene
Polymer International, 1993Abstract A novel approach is proposed for estimating the average molecular weight between crosslinks (M̄ c ) from the functionality distribution of hydroxyl‐terminated polybutadiene ( HTPB ). The functionality distribution of four free‐

Chitin based polyurethanes using hydroxyl terminated polybutadiene, Part II: Morphological studies
International Journal of Biological Macromolecules, 2013Chitin-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, 2013Chitin 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 ...
