TRISPHENOLS

摘要

New trisphenols and their preparation by reacting the diacyl compound of dimeric p-isopropenylphenol or of a polycarbonate with a phenol in the presence of a strong acid catalyst at temperatures between -20 and 30.degree.C. The products of the process can be used for various technical purposes. Their reaction with epichlorohydrin yields highly heat resistant epoxide resins. Ethoxylation and propoxylation products of the new trisphenols are excellent textile additives and levelling agents for textile dyeing. The products are also suitable for the reversible cross-linking of polyurethanes.
