PROCESS FOR PREPARATION OF PHENOL-ANILINE- FORMALDEHYDE RESIN USING STRONG BASE MACRORETICULAR POLYMER SUPPORTED CATALYSTS,

摘要

The invention relates to method of synthesis of phenol-aniline-formaldehyde resins using heterogeneous base catalyst having a polymeric backbone. The catalyst comprises of a tertiary amine moiety as the reactive functional group present on the crosslinked polymer backbone. Heterogeneous catalyst of the present invention can be removed easily by filtration and available for re-use without loss in catalytic activity.[IN-DEL-2010-02771A]
