Методика

As the polyisocyanate constituting the urethane resin, there can be mentioned, for example, hexamethylene diisocyanate, xylylene diisocyanate, 1-methyl-2,4-diisocyanate, cyclohexane phenylene diisocyanate, tolylene diisocyanate, chlorophenylene diisocyanate, diphenylmethane-4,4'-diisocyanate, naphthalene-1,5-diisocyanate, triphenylmethane-4,4',4"-triisocyanate, xylylene-2,2'-diisocyanate, isopropylbenzene-2,4-diisocyanate, an adduct of 1 mole of trimethylol propane and 3 moles of tolylene diisocyanate, and high-molecular-weight polyisocyanates obtained by polymerization of the foregoing polyisocyanates.
