Glycerin, toluene diisocyanate (TDI), and polyglycol (PG) were reacted at various molar ratios to produce glycerin-terminated urethane prepolymers of different molecular weights. The prepolymers were mixed with equivalent phenol-blocked trimethylol propane-TDI-urethane triisocyanate in rn-cresol to

The synthesis and structureโproperty relationships of one-component urethane adhesives were studied. NCO-terminated urethane prepolymers were prepared from monomeric diphenylmethane-4,4โฒ-diisocyanate, difunctional polypropyleneglycol polyols and their mixtures.
