Process for the production of prepolymers containing isocyanate groups, prepolymers produced by this process and their use |
| abstract |
The present invention is directed to a process for the production of prepolymers containing free tertiary isocyanate groups by reacting n (a) an organic diisocyanate containing one isocyanate group attached to a primary aliphatic carbon atom and an isocyanate group attached to a tertiary aliphatic or cycloaliphatic carbon atom with n (b) a polyester polyol having a molecular weight of 800 to 12,000 and a hydroxyl functionality of 2 to 6 at an NCO/OH equivalent ratio of 1.6:1 to 2:1 to provide prepolymers having a molecular weight of about 1000 to 3000 and an NCO content of about 4 to 12%. n The present invention is also directed to the prepolymers containing free isocyanate groups obtained by this process and to their use for the production of polyurethane lacquers and coatings. |
