Abstract
1286206 Curing epoxy resins HITACHI Ltd and HITACHI CHEMICAL CO Ltd 22 May 1970 [26 May 1969 (2)] 25040/70 Heading C3B A curable composition comprises an epoxy resin, a polycarboxylic acid anhydride and a curing promoter of formula in which M is P or As; R 1 to R 4 which may be the same or different are each alkyl, hydroxyethyl, alkenyl or aryl; R 5 is alkyl, alkenyl or aryl or when M is M and R 1 , R 2 , R 3 and R 4 are Ph, R 4 is 2-hydroxyethyl or Examples of suitable anhydrides are methylendomethylenetetrahydrophthalic, hexa- or tetrahydrophthalic, dodecenyl – succinic, phthalic or trimellitic anhydrides. Examples of I are tetraphenylphosphonium tetraphenylborate, (n – butyl)triphenylphosphonium tetraphenylborate, (ethyl)triphenylphosphonium tetraphenylborate, tetra – n – butylphosphonium borate, p – xylene – bis – (triphenylphosphonium) tetraphenylborate and tetraphenylarsonium tetraphenylborate. The composition may also comprise a filler, e.g. 5-60% by volume of the total composition of a filler having a granularity of <44 Á and 10-70% by volume of a filler having granularity >64 Á. I may be present at 0À1-10 parts by wt. per 100 parts by wt. of epoxy resin. The anhydride may be present at 0À001-1À5 moles per epoxide equivalent of the epoxy resin. Uses.-Electrical insulation.
