Rapid setting polyurethanes from diols and polyisocyanates in the presence of a hydroxyl-containing halogenated aliphatic compound

Claim 1

A RIGID, NON-CELLULAR COMPOSITION HAVING A DENSITY OF AT LEAST ABOUT 1 GRAM/CC WHICH IS DEMOLDABLE, WITHOUT THE APPLICATION OF AN EXTERNAL SOURCE OF HEAT, WITHIN ABOUT 5 MINUTES AFTER ADMIXTURE OF THE COMPONENTS OF THE COMPOSITION WHICH IS THE REACTION PRODUCT OF A POLYURETHANE-FORMING COMPOSITION COMPRISING A. A DIHYDROXYL-CONTAINING COMPOUND HAVING A HYDROXYL EQUIVALENT WEIGHT OF LESS THAN ABOUT 3250; B. AN ORGANIC POLYISOCYANATE HAVING AN NCO FUNCTIONALITY OF AT LEAST ABOUT 2.5; C. A LIQUID MODIFIER COMPOUND OR MIXTURE OF SUCH COMPOUNDS AND WHICH MODERATES THE REACTION EXOTHERM SELECTED FROM THE GROUP CONSISTING OF MONOHYDROXYLCONTAINING HALOGENATED ALIPHATIC COMPOUNDS HAVING AN ATMOSPHERIC BOILING POINT BELOW ABOUT 150*C AND AN OH EQUIVALENT WEIGHT OF LESS ABOUT 500; AND D. AN ORGANOMETALLIC CATALYST; WHEREIN COMPONENT (A) AND (B) ARE PRESENT IN QUANTITIES SUCH THAT THE NCO:OH RATIO IS FROM ABOUT 0.8:1 TO ABOUT 1.5:1, COMPONENT (C) IS PRESENT IN QUANTITIES OF FROM ABOUT 0.1 TO ABOUT 10 PERCENT BY WEIGHT OF THE COMBINED WEIGHTS OF COMPONENTS (A), (B) AND (C); AND COMPONENT (D) IS PRESENT IN QUANTITIES OF FROM ABOUT 0.02 TO ABOUT 5.0 PERCENT BY WEIGHT OF THE COMBINED WEIGHT OF COMPONENTS (A), (B) AND (C).
