Tertiary aminophenol catalytic polyurethane production

Claim 1

A PROCESS FOR PREPARING A POLYURETHANE PLASTIC WHICH COMPRISES REACTING (1) AN ORGANIC POLYFUNCTIONAL COMPOUND SELECTED FROM THE GROUP CONSISTING OF DIISOCYANATES AND DIISOTHIOCYANATES, (2) A COMPOUND CONTAINING A PLURALITY OF ACTIVE HYDROGEN ATOMS AS DETERMINED BY THE ZEREWITINOFF METHOD SELECTED FROM THE GROUP CONSISTING OF GLYCOLS, PRIMARY AND SECONDARY AMINES, DICARBOXYLIC ACIDS, HYDROXYAMINES, HYDROXYCARBOXYLIC ACIDS, AMINOCARBOXYLIC ACIDS AND GLYCERIL, AND (3) AN ORGANIC COMPOUND CONTAINING TERMINAL HYDROXYL GROUPS SELECTED FROM THE GROUP CONSISTING OF POLYESTERS AND POLYETHERS HAVING AN AVERAGE MOLECULAR WEIGHT BETWEEN 300 AND 6000 IN THE PRESENCE OF A HEAT-SENSITIVE ACID ADDITION SALT OF 2,4,6-TRIS(DIALKYLAMINOALKYL)PHENOLS, IN SUCH AMOUNTS THAT THE RATIO OF TOTAL ISOCYANATO AND ISOTHIOCYANATO GROUPS TO TOTAL HYDROXYL GROUPS IS GREATER THAN 1:1 AND HEATING TO A TEMPERATURE BETWEEN 40*C. AND 300*C., AND WHEREIN HEATSENSITIVE IS DEEMED TO MEAN THAT SAID SALT IS DECOMPOSABLE TO FORM THE FREE TERTIARY AMINOPHENOL UPON THE APPLICATION OF SAID HEAT.
