Modified diphenylmethane reaction

TABLE 1. Scoping Reactions for Preparation of Urctonimine-Modified Isocyanate Using 93.80% 4,4 -Diphenylmethane Diisocyanate Containing 6.20% 2,4 -Diphenylmethane Diisocyanate Conducted at 105-108°C Using 3-Methyl-l-phenyl-3-phosphoIene-l-oxide as Catalyst... [Pg.283]

PUs are formed as a result of a condensation or an adduction reaction between isocyanates and polyols [polyesters or polyethers with terminal hydroxyl (OH) groups, castor oil or tall oil]. If both components are more than difunctional, thermosetting end products are produced. Many auxiliary substances are also used in the manufacture of PU products. The hardening process can be modified by heat or with a catalyst [diamino diphenylmethane or meth-ylenedianiline (MDA), triethylenediamine, triethyl-amine, cobalt naphthenate or nickel salts].
