Polyether-modified polyisocyanate composition |
| abstract |
The present invention relates to a polyether-modified polyisocyanate composition, which is obtainable by reacting a system containing the following components: a) a polyisocyanate having an isocyanate group functionality of 2-4.5; b) a polyoxyalkylene monoether alcohol; and c) optionally a catalyst; the polyoxyalkylene monoether alcohol has a number-average molecular weight of 900g/mol-2000g/mol and an oxypropylene group content of 45 wt.%-100 wt.%, relative to the total weight of the oxyalkylene group of the polyoxyalkylene monoether alcohol; the system has an equivalent ratio of isocyanate group to hydroxyl group of 5:1-110:1; the polyisocyanate composition has the following characteristics: i) the average isocyanate functionality is 1.8-4.1; ii) the isocyanate group content is 8-20 wt.%; and iii) the amount of the polyoxyalkylene monoether structure is greater than 10 wt.% and less than 50 wt.%, for characteristics ii) and iii), relative to the total weight of the polyisocyanate composition. |
