Claim 1

A NON-ELASTOMERIC, NON-CELLULAR, SOLID POLYMER HAVING A DENSITY OF AT LEAST ABOUT 1 GRAM/CC AND AN ELONGATION VALUE OF LESS THAN ABOUT 80 PERCENT 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 775 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 ORGANIC PHOSPHATES, ORGANIC PHOSHITES AND ORGANIC PHOSPHONATES 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 SO 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 PERCENT WITH THE PROVISO THAT WHEN COMPONENT (B) IS AN NCO--CONTAINING PREPOLYMER CONTAINING LESS THAN ABOUT 40 PERCENT NCO GROUPS BY WEIGHT, COMPONENT (C) IS PRESENT IN QUANTITIES OF FROM ABOUT 10 TO ABOUT 50 PERCENT BY WEIGHT OF THE SUM OF COMPONENTS (A),(B) AND (C); AND COMPONENT (D) IS PRESENT IN QUANTITIES OF FROM ABOUT 0.01 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 APPPLICATION OF AN EXTERNAL SOURCE OF HEAT, AFTER ADMIXTURE OF SAID COMPOSITION.
