| titleOfInvention | Process for preparing isocyanate homopolymers containing uretdione groups |
| abstract | The present invention relates to a process for preparing an isocyanate homopolymer containing uretdione groups, wherein a homopolymerization reaction of a starting isocyanate is catalyzed by using a phosphinoboron compound of the formula (I) as a catalyst, whereby an isocyanate having a uretdione group A solution of the homopolymer is obtained, and then the solution is separated to obtain an isocyanate homopolymer containing uretdione groups. The isocyanate homopolymer containing uretdione groups produced by the above method has a large amount of urethane groups and the dependence of the amount on the conversion of the starting isocyanate is remarkably improved with a low chromaticity: (I) |
