| titleOfInvention | Hydroxylamino polymer and method for the production thereof |
| abstract | The present invention relates to a method for producing a hydroxylamino polymer, comprising the steps: a) reacting an H-functional starter compound bearing at least one Zerewitinoff-active H atom with an unsaturated cyclic carboxylic acid anhydride to form a prepolymer bearing carboxyl groups, b) reacting the prepolymer bearing carboxyl groups with at least one epoxy compound to obtain a prepolymer bearing hydroxyl groups, c) adding a primary amine and/or ammonia to the double bond of the prepolymer bearing hydroxyl groups obtained according to step b) to obtain the hydroxylamino polymer, wherein the molar ratio between the carboxylic acid anhydride and the number of Zerewitinoff-active H atoms in the H-functional starter compound is selected such that to the greatest extent possible all Zerewitinoff-active H atoms of the H-functional starter compound are reacted. The invention further relates to a hydroxylamino polymer that can be obtained according to the aforementioned method, wherein the ratio between the molar quantity of the unsaturated cyclic carboxylic acid anhydride and the number of Zerewitinoff-active H atoms of the H-functional starter compound is at least approximately 0.9:1, and further relates to the use of said hydroxylamino polymer for producing a polyurethane-urea polymer. |
