摘要： Urethane-filled compositions are produced by reacting a dicyclohexylmethane diisocyanate residue or a dicyclohexylmethane diisocyanate residue containing mixture with a monofunctional alcohol containing at least one ether group in an amount such that the equivalent ratio isocyanate groups to hydroxyl groups is from about 0.9:1 to about 1:0.9. The diisocyanate residue or residue-containing mixture must contain at least 20% by weight monomeric diisocyanate and have a total NCO content of at least 10%. The diisocyanate residue is produced by phosgenating dicyclohexylmethane diamine in which less than 20% polymeric diamine is present. The urethane filled compositions produced in this manner may then be dissolved in either a polyol or a polyisocyanate and subsequently used to produce polyurethanes in known manner.
