POLYHYDROXYAMINOPHENYLENE SULFIDES AS A HARDENER OF EPOXY OLIGOMERS AND A METHOD OF THEIR SYNTHESIS Russian patent published in 1995 - IPC

Abstract RU 2044003 C1

FIELD: organic chemistry. SUBSTANCE: product: polyhydroxyaminophenylene sulfides of the general formula where n 10-20, x 1-2; k:l (1-6):(1-2) were synthesized by polycondensation of sulfur with a mixture of aniline with phenol at boiling of reaction mass up to boiling ceasing followed by heating at 200-240 C for 10-48 h at the molar ratio sulfur aniline phenol (1.5-4.0):(1-6):(1-2), respectively. Synthesized compounds were used as epoxy oligomer hardeners and intermediate product in the process of other type of cross-linked polymer synthesis. EFFECT: improved method of synthesis. 2 tbl
