Abstract 1. A SOLID, RIGID, NON-CELLULAR URETHANE POLYMER HAVING A DENSITY OF AT LEAST ABOUT 1 GRAM/CC. RESULTING FROM ADMIXTURE OF THE COMPONENTS OF A COMPOSITION COMPRISING A. AN ACTIVE HYDROGEN-CONTANING COMPONENT SELECTED FROM (1) A POLYETHER POLYOL HAVING A HYDROXYL EQUIVALENT WEIGHT OF BETWEEN ABOUT 75 AND ABOUT 230 AND CONTAINING FROM 3 TO ABOUT 8 HYDROXYL GROUPS PER MOLECULE, (2) A DIHYDROXYL-CONTAINING COMPOUND HAVING A HYDROXYL EQUIVALENT WEIGHT OF LESS THAN ABOUT 250, AND (3) MIXTURES THEREOF; B. AN ORGANIC POLYISOCYANATE; C. A MODIFIER CMPONENT WHICH MODERATES THE REACTION BETWEEN COMPONENTS (A) AND (B) WITHOUT SUBSTANTIAL REACTION THEREWITH COMPRISING (1) 50-100% BY WEIGHT OF, AS A MODIFIER, A SUBSTITUTED AROMATIC COMPOUND CONTAINING AT LEAST ONE AROMATIC HYDROXYL GROUP AND AT LEAST ONE SUBSTITUENT WHICH CONTAINS AT LEAST 3 CARBON ATOMS ATTACHED TO EACH IRNG CONTAINING AN AROMATIC HYDROXYL GROUP OR MIXTURES THEREOF; AND (2) 0-50% BY WEIGHT OF A CO-MODIFIER SELECTED FROM (A) ORGANIC LIQUID COMPOUNDS HAVING A BOILING POINT ABOUT 150*C., (B) LIQUID HALOGENATED ALIPHATIC COMPOUNDS CONTAINING A HYDROXYL GROUP AND HAVING A BOILING POINT OF LESS THAN ABOUT 150*C., OR (C) MIXTURES THEREOF; D. A MON-AMINE CATALYST FOR URETHANE FORMATION; WHEREIN COMPONENTS (A) AND (B) ARE PRESENT IN QUANTITIES SUCH THAT THE NCO:OH RATIO IS FROM ABOUT 0.8:1 TO ABOUT 1.5:1; THE QUANTITIES OF COMPONENT 8C) BEING FROM ABOUT 10 TO ABOUT 50 PERCENT BY WEIGHT BASED UPON THE COMBINED WEIGHT OF COMPONENTS (A-2) IS EMPLOYED AS THE SOLE COMPONENT (D) NEED NOT BE PRESENT; AND WHEREIN SAID POLYMER CAN BE DEMOLDED WITHIN LESS THAN ABOUT 5 ALITY OF AT LEAST ABOUT 2.5; AND WHEN COMPONENT (A-1) IS AN AMINE INITIATED POLYOL AND IS EMPLOYED AS THE SOLE COMPONENT OF COMPONENT (A), THN COMPONENT (D) NEED NOT BE PRESENT; AND WHEREIN SAID POLYMER CAN BE DOMOLDED WITH LESS THAN ABOUT 5 MINUTES, WITHOUT THE APPLICATION OF AN EXTERNAL SOURCE OF HEAT, AFTER ADMIXTURE OF THE COMPONENTS OF SAID COMPOSITION.
