METHOD FOR PRODUCTION OF POLY(BIS-MALEIMIDE) PREPOLYMERS Russian patent published in 2002 - IPC

Abstract RU 2186793 C2

FIELD: polymer production. SUBSTANCE: prepolymers are prepared via interaction of N,N'-bis- maleimide with primary aromatic diamines in organic solvent on heating in presence of 0.1-2.0 wt.% of ultrafine (20-20 nm) diamond powder. EFFECT: ensured homogeneity of prepolymers and stabilized physico-mechanical properties within a wide temperature range. 2 tbl
