Title:
REACTIVE COMPONENT CONTAINING STABILIZER FOR POLYURETHANE FOAM, NOVEL STABILIZER AND MANUFACTURE
Document Type and Number:
Japanese Patent JPS5819320
Kind Code:
A
Abstract:
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.
