PROCESS FOR PRODUCING A EPOXY-RESINS

摘要

The high functional epoxy resin is made by; (a) dissolving epoxy resin(II) in nonpolar solvent; (b) mixing with a little benzoylperoxide catalyst added;(c) obtaining epoxy resin containing brome(III) from adding 1-bromo-2,5- C4H4Br-NO2; (d) dissolving epoxy resin containing brome(III) in diethylether or tetrahydrofuran with magnesium;(e) mixing with O-methylhydroxylamine added;(f) obtaining epoxy resin(IV); (g) dissolving epoxy resin(IV) in DMF with maleicimide and reacting for several hrs. The epoxy resin has high stress relaxation, heat and moisture resistance.
