Rapid setting non-elastomeric polyurethane compositions prepared in the presence of non-hydroxyl containing polyoxyalkylene compounds

Claim 1

A NON-ELASTOMERIC, NON-CELLULAR SOLID POLYMER HAVING A DENSITY OF AT LEAST ABOUT 1 GRAM/CC AND A PERCENT ELONGATION OF LESS THAN ABOUT 80, RESULTING FROM ADMIXTURE OF THE COMPONENTS OF A COMPOSITION COMPRISING: A. A POLYETHER POLYOL HAVING FROM 3 TO ABOUT 8 HYDROXYL GROUPS AND A HYDROXYL EQUIVALENT WEIGHT BETWEEN ABOUT 75 AND ABOUT 230, B. AN ORGANIC POLYISOCYANATE, C. A LIQUID MODIFIER COMPOUND HAVING A BOILING POINT ABOVE ABOUT 150*C SELECTED FROM THE GROUP CONSISTING OF NONHYDROXYL-CONTAINING POLYOXALKYLENE COMPOUNDS AND MIXTURES THEREOF, AND D. A NON-AMINE-CONTAINING CATALYST FOR URETHANE FORMATION, WHICH IS AN ORGANO METAL COMPOUND; WHEREIN COMPONENTS (A) AND (B) ARE PRESENT IN AMOUNTS OF AS TO PROVIDE AN NCO:OH RATIO OF FROM ABOUT 0.8:1 TO ABOUT 2:1, COMPONENT (C) IS PRESENT IN QUANTITIES OF FROM ABOUT 20 TO ABOUT 50% WITH THE PROVISO THAT WHEN COMPONENT (B) IS AN NCO-CONTAINING PREPOLYMER CONTAINING LESS THAN ABOUT 40% NCO BY WEIGHT, COMPONENT (C) IS PRESENT IN QUANTITIES OF FROM ABOUT 10% TO ABOUT 50% BY WEIGHT OF THE SUM OF COMPONENTS (A), (B) AND (C); AND COMPONENT (D) IS PRESENT IN QUANTITIES OF FROM ABOUT 0.2 TO ABOUT 10 PERCENT BY WEIGHT OF THE SUM OF THE WEIGHTS OF COMPONENTS (A), (B) AND (C); AND WHEREIN SAID POLYMER CAN BE DEMOLDED WITHIN LESS THAN ABOUT 5 MINUTES, WITHOUT THE APPLICATION OF AN EXTERNAL SOURCE OF HEAT, AFTER AMIXTURE OF SAID COMPOSITION.
