Claims
- 1. A polyol blend comprising (i) from about 20 percent to about 85 percent by weight of said blend of an amine diol, or mixture of amine diols selected from the formula ##STR3## wherein R is an aliphatic radical having from 8 to 18 carbon atoms, inclusive, each R.sub.1 is independently selected from the group consisting of hydrogen and methyl, x and y each independently have an average value between about 4 and about 15 inclusive; and (ii) from about 15 percent to about 80 percent by weight of a primary hydroxyl polyol characterized by a molecular weight of from about 60 to about 1000.
- 2. A miscible polyol blend comprising at least about 25 percent by weight of a fluorocarbon blowing agent and the balance being a polyol blend set forth in claim 1.
- 3. A polyol blend comprising from about 1 percent to about 6 percent by weight of water and from about 94 percent to about 99 percent by weight of the polyol blend set forth in claim 1.
- 4. A polyol blend comprising (i) from about 20 percent to about 85 percent by weight of said blend of an amine diol, or mixture of amine diols selected from the formula ##STR4## wherein R is an aliphatic radical having from 8 to 18 carbon atoms, inclusive, and x and y each independently have an average value between about 4 and about 15 inclusive; and (ii) from about 15 percent to about 80 percent by weight of a primary hydroxyl diol having a molecular weight of from about 60 to about 1000.
- 5. A miscible polyol blend comprising at least about 25 percent by weight of a fluorocarbon blowing agent and the balance being a polyol blend set forth in claim 4.
- 6. A polyol blend according to claim 4 wherein the primary hydroxyl diol (ii) has a molecular weight of from about 60 to about 800.
- 7. A polyol blend comprising (i) from about 20 percent to about 85 percent by weight of said blend of the ethoxylated cocoamine diol mixture obtained from the reaction of about 15 moles of ethylene oxide with cocoamine; and (ii) from about 15 percent to about 80 percent by weight of a primary hydroxyl diol having a molecular weight of from about 60 to about 800.
- 8. A polyol blend according to claim 7 wherein the primary hydroxyl diol (ii) is diethylene glycol.
- 9. A polyol blend according to claim 7 wherein the primary hydroxyl diol (ii) is a polyoxydiethylene adipate glutarate polyester diol having a molecular weight from about 400 to about 600.
- 10. A polyol blend according to claim 7 wherein the primary hydroxyl diol (ii) comprises a mixture of from about 30 percent to about 50 percent by weight of diethylene glycol and from about 50 percent to about 70 percent by weight of a polyoxydiethylene adipate glutarate polyester diol having a molecular weight from about 400 to about 600.
- 11. A miscible polyol blend comprising at least about 25 percent by weight of a fluorocarbon blowing agent and the balance being a polyol blend set forth in any one of claims 7, 8, 9, or 10.
- 12. A polyol blend comprising from about 2 to about 20 percent by weight of an isocyanate trimerization catalyst and from about 80 to about 98 percent by weight of the polyol blend according to claim 2 or 3.
