Abstract: EPOXY CELLULAR PLASTICS ARE OBTAINED BY FOAMING EPOXY RESINS WITHOUT EXTERNAL HEATING IN THE PRESENCE OF LOWBOILING ORGANIC SOLVENTS AS BLOWING AGENTS AND COMPLEX COMPOUNDS OF BORON TRIFLUORIDE AND AROMATIC AMINES AS POLYMERIZATION CATALYSTS. THE BORON TRIFLUORIDE COMPLEXING AGENTS USED ARE SELECTED FROM 2-CHLORANILINE, 3-CHLORANILINE, 4-CHLORANILINE, 2,4-DICHLORANILINE, 2-CHLORO-4METHYLANILINE, 2-BROMANILINE, 2 - NITOR - ANILINE, 3 - NITROANILINE, 4-NITRO-ANILINE, 4-AMINOBENZOIC ACID ETHYL ESTER, 2-METHOXY-4-CHLORANILINE, 4-CHLORO-DIPHENYLAMINE, 2,2''DICHLORO-BENZIDINE, 4-CHLORO-1-NAPHTHYLAMINE, 1-CHLORO-2NAPHTHYLAMINE AND 4-METHOXY-1-NAPHTHYLAMINE. LOW TEMPERATURE CURES ARE ACHIEVED WHICH PRODUCE CELLULAR PLASTICS HAVING IMPROVED PROPERTIES.
