## Abstract Polyurethanes have been prepared from the reactions of the diimidazole and ditriazole adducts of 2,4βtoluene diisocyanate and ethylene glycol or polyols. Suitable formulations have been developed from these components which are useful in preparing polyurethane coatings and foams. Imidaz
The reaction of dye with toluene diisocyanate and dimethyldichlorosilane in the presence of other additives to form a colored siloxane-based polyurethane (PU) ionomer has been proven to occur by infrared spectra. In aqueous solution, the numberaverage particle size for the colored siloxane-based PU
