STABILISER-CONTAINING REACTIVE COMPONENTS FOR PU-FOAMS,NEW STABILISERS AND A PROCESS FOR PRODUCING THESE STABILISERS |
摘要 |
The invention relates to stabilizer-containing reactive components for the production of polyurethane foams having little or no tendency towards core discoloration which are characterized by a stabilizing addition of monomeric and/or oligomeric derivatives of the diphenylamine series, including the phenothiazine series. The invention also relates to new stabilizers of the diphenylamine and/or phenothiazine series and to a process for their production, characterized in that aromatic amines of the diphenylamine and/or phenothiazine series are reacted with bifunctional halogen derivatives, diols, bis-ethers or bis-esters or with bis-olefins formed therefrom at elevated temperatures in the presence of strong acids and the amines are optionally further alkylated. |
