| titleOfInvention | Use of alcohols containing at least two urethane groups for producing polyether carbonate polyols |
| abstract | The invention relates to a method for producing polyether carbonate polyols by adding alkylene oxides and carbon dioxide to H-functional starter compounds, characterized in that at least one alcohol containing at least two urethane groups is used as H-functional starter compound. The invention also relates to polyether carbonate polyols containing structural units of the formula (IV), in which: r 1 Means straight-chain or branched C 2 -to C 24 Alkylene which is optionally interrupted by a heteroatom O, S or N and which may be substituted, preferably CH 2 ‑CH 2 Or CH 2 ‑CH(CH 3 )；R 2 Means straight-chain or branched C 2 -to C 24 Alkylene radical, C 3 -to C 24 -cycloalkylene radical, C 4 -to C 24 Arylene radical, C 5 -to C 24 -aralkylene, C 2 -to C 24 -alkenylene, C 2 -to C 24 Alkynylene, each of which may optionally be interrupted by a heteroatom such as O, S or N and/or each may be substituted by alkyl, aryl and/or hydroxy, preferably C 2 -to C 24 -an alkylene group; r 3 Means H, straight-chain or branched C 1 -to C 24 Alkyl radical, C 3 -to C 24 -cycloalkyl, C 4 -to C 24 -aryl, C 5 -to C 24 -aralkyl group, C 2 -to C 24 -alkenyl, C 2 -to C 24 Alkynyl groups, each of which may be optionally interrupted by heteroatoms such as O, S or N and/or each of which may be substituted by alkyl, aryl and/or hydroxy, preferably H; r 4 Means H, straight-chain or branched C 1 -to C 24 Alkyl radical, C 3 -to C 24 -cycloalkyl, C 4 -to C 24 -aryl, C 5 -to C 24 -aralkyl group, C 2 -to C 24 -alkenyl, C 2 -to C 24 Alkynyl groups, each of which may be optionally interrupted by heteroatoms such as O, S or N and/or each of which may be substituted by alkyl, aryl and/or hydroxy, preferably H; r 5 Means straight-chain or branched C 2 -to C 24 Alkylene which may optionally be interrupted by heteroatoms such as O, S or N and may be substituted, preferably CH 2 ‑CH 2 Or CH 2 ‑CH(CH 3 ) (ii) a And wherein R 1 To R 5 May be the same or different from each other. |
