METHOD FOR PRODUCTION OF THREE- AND MORE FUNCTIONAL OLIGOESTER (METH)ACRYLATE AS MONOMER FOR PHOTOSENSITIVE MATERIALS Russian patent published in 1996 - IPC

Abstract RU 2053219 C1

FIELD: organic chemistry. SUBSTANCE: polyfunctional epoxy oligoether is used as reagent 1, acryl or methacryl acid is used as reagent 2. Their interaction is carried out at 95-100 C in the presence of catalyst and inhibitor of radical polymerization. 2,6,6-trio-dimethylaminomethyl phenol is used as said catalyst, hydroquinone being used as said inhibitor. Reaction mixture contains (mass %): epoxy oligoether 73.324-84.576, (meth)acryl acid 15.022-26.424, catalyst 0.072-0.536, hydroquinone 0.074-0.215. EFFECT: improves efficiency of method.
