| titleOfInvention | PROCEDURE FOR THE PRODUCTION OF POLYURETHANE - POLYURES CONTAINING SIDE CHAINS AND WATER DISPERSIONS OF THE SAME. |
| abstract | The present invention relates to a process for the production of aqueous polyurethane-polyurea dispersions for which A) first A1) primary and / or secondary monoamines or diamines are reacted with A2) cyclic carbonates that precisely contain a group hydroxyl, where the molar ratio of A1) and A2) is such that in the case of monoamines A1) the theoretical ratio of all primary and secondary amine groups to cyclic carbonate groups is between 0.8 to 1.2 and in the case of diamines Al) the theoretical ratio of all primary and secondary amine groups to cyclic carbonate groups is between 1.8 to 2.2, and A3) in the case of diamines A1), the remaining groups of primary and secondary amines are reacted with compounds that accurately carry a functional group that reacts with primary or secondary amines in an addition reaction, so that no re-group is formed isocyanate active, where the molar amount of A3) is such that the theoretical ratio of all the theoretically remaining groups of primary and secondary amines after the reaction of A1) and A2) to the amine reactive groups in A3 ) is between 0.8 to 1.2, where the reaction with A3) can take place afterwards, simultaneously with or before the reaction with A2), B) subsequently a polyurethane prepolymer containing NCO groups is produced by the reaction of B1) polyisocyanates with B2) polyols and / or polymeric polyamines having number average molecular masses of more than 400 to 8000 g / moles and B3) optionally low molecular weight compounds with number average molecular masses of 17-400 g / moles selected from between the group consisting of mono- and polyols, mono- and polyamines and amino alcohols, and B4) optionally ionic or potentially ionic hydrophilizing compounds reactive with isocyanate and / or compounds non-ionic hydrophilicizers reactive with isocyanate, and B5) the reaction products of A), C) the prepolymer of B) is dispersed in water, and D) optionally the remaining free NCC groups of the prepolymer with monoamines, polyamines, hydrazine and / or isocyanate reactive hydrazides, wherein the molar amount thereof is such that the theoretical ratio of the isocyanate reactive NH groups to the NCC groups is between 0 to 1.2, wherein said reaction D) can take place to a certain degree. either completely before or during the dispersion stage C). |
