Claims
- 1. An isocyanurate group-containing polyisocyanate corresponding to the formula ##STR11## wherein R represents a radical corresponding to the formula ##STR12## wherein R.sub.1 represents an alkyl radical containing 1 to 4 carbon atoms,
- R.sub.2 and R.sub.3 which may be the same or different represent a linear or branched divalent saturated hydrocarbon radical containing 1 to 4 carbon atoms,
- R.sub.4 represents hydrogen or an alkyl radical containing 1 to 4 carbon atoms,
- R.sub.5 represents a linear or branched, saturated divalent hydrocarbon radical containing 1 to 4 carbon atoms, and
- n represents 0 or 1.
- 2. The isocyanurate group-containing polyisocyanate of claim 1 wherein
- R.sub.1 represents a methyl radical,
- R.sub.2 and R.sub.3 which may be the same or different represent linear divalent saturated hydrocarbon radicals containing from 1 to 3 hydrocarbon atoms, provided that the sum of the number of carbon atoms in the radicals R.sub.2 and R.sub.3 is 4 or 5,
- R.sub.4 represents a hydrogen atom,
- R.sub.5 represents a linear or branched, saturated divalent hydrocarbon radical containing from 1 to 3 carbon atoms, and
- n represents 0 or 1.
- 3. The isocyanurate group-containing polyisocyanate of claim 2 wherein
- R.sub.2 represents ethylene or trimethylene and the sum of the number of carbon atoms in the radicals R.sub.2 and R.sub.3 is 4, and
- n represents 0.
- 4. The isocyanurate group-containing polyisocyanate of claim 2 wherein
- R.sub.2 and R.sub.3 both represent ethylene,
- R.sub.5 represents isoproylene with the branched carbon atom vicinal to the cyclohexane ring, and
- n represents 1.
