| titleOfInvention | A method of making polyurethane and said polyurethane |
| abstract | A polyurethane is made by reacting (1) a reactive-hydrogen-containing organic polymer of mol. wt. from 400 to 10,000 with an excess of (2) an organic polyisocyanate to form an isocyanate-containing polymer which is then reacted with (3) a cross-linking agent, in the presence of (4) a catalyst which is a mercapto derivative of a thiazole, thiazoline, oxazole, imidazole or imidazoline, in an amount of 0.5 to 10 parts (by wt.) per 100 parts of (1). The preferred polymer (1) is a polyester-, polyether- or hydrocarbon-polyol. Cross-linking agents (3) disclosed are methylene-dianiline, o-dianisidine, methylene-bis-(o-chloroaniline), o-dichlorobenzidine and glycols. Numerous examples of catalysts (4) are given. Examples (1-3) describe the preparation of a prepolymer by reacting a mixed adipate with toluene diisocyanate and dissolving the prepolymer in a solvent mixture. In the other examples the prepolymer solutions are mixed with various cross-linkers (3) and catalysts (4) to yield polyurethane films. |
