Claims
- 1. A process for the preparation of a polyisocyanate polyaddition product which comprises reacting
- (a) at least one diisocyanate or an isomeric mixture thereof having an isocyanate content of about 30 to 48% and corresponding to formula (I) ##STR9## wherein R.sub.1 represents an alkyl group having from 1 to 4 carbon atoms, R.sub.2 and R.sub.3, which may be identical or different, represent linear or branched chain, divalent hydrocarbon groups having 1 to 4 carbon atoms,
- R.sub.4 represents hydroben or an alkyl group having 1 to 4 carbon atoms,
- R.sub.5 represents a linear or branched chain, saturated, divalent hydrocarbon group having 1 to 4 carbon atoms, and
- n represents 0 or 1, with
- (b) a compound containing isocyanate-reactive hydrogens.
- 2. The process of claim 1 wherein
- R.sub.1 represents a methyl group, R.sub.2 and R.sub.3 represent identical or different, linear divalent, saturated hydrocarbon groups having 1 to 3 carbon atoms, with the prviso that the sum of the number of carbon atoms of groups R.sub.2 and R.sub.3 amounts to 3 or 4, and
- R.sub.4 represents hydrogen or a methyl group.
- 3. The process of claim 1 wherein said diisocyuanate comprises 1-isocyanato-1methyl-4(3)-isocyanatomethyl -cyclo-hexane.
- 4. The process of claim 1 wherein said diisocyanate comprises 1-isocyanato-1-methyl-4-(4-isocyanatobut-2-yl)-cyclohexane.
- 5. The process of claim 1 wherein said diisocyanate comprises 1-isocyanato-1,2,2-trimethyl-3-(2-isocyanatoethyl)-cyclopentane.
- 6. The process of claim 1 wherein said polyisocyanate polyaddition product is a polyurethane and component (b) comprises a compound containing hydroxyl groups.
- 7. The process of claim 1 wherein said diisocyhanate is blocked with a blocking agent for isocyanate groups.
- 8. The process of claim 6 wherein said diisocyanate is blocked with a blocking agent for isocyanate groups.
- 9. The process of claim 3 wherein said polyiscyanate polyaddition product is a polyurethane and component (b) comprises a compound containing hydroxyl groups.
- 10. The process of claim 9 wherein said diisocyanate is blocked with a blocking agent for iscoyanate groups.
- 11. The polyisocyanate polyaddition product produced in accordance with claim 1.
- 12. The polyisocyanate polyaddition product produced in accordance with claim 3.
- 13. The polyisocyanate polyaddition product produced in accordance with claim 6.
- 14. The polyisocyanate polyaddition product produced in accordance with claim 9.
