EPOXIDE OLIGOMER MODIFIED BY N-DI(TERT-BUTYLPEROXYMETHYL)MONOETHANOLAMINE

A new oligoperoxide (OPN), has been obtained by the condensation of an epoxide oligomer based on 4,4'-dihydroxy-2,2-diphenylpropane catalyze d by [BF3 .(C2H5O] at 318 K in dry benzene. The structure of the OPN p roduct was confirmed by IR spectroscopy and chemical analysis, Thermog ravimetric analysis showed that the presence of nitrogen decreases the stability of the O-O-bond for the OPN relative to that in ordinary pe roxide oligomers (OF). OPN may be used as a curing agent for polymeric compositions having unsaturated polymers (UP), The formation of a spa ce polymer from 363 to 383 K occurs due to a polymerization process wh ich is initiated by the decomposition of peroxy groups. In curing at h igher temperatures (383 - 423 K) other functional groups of OPN also p articipate in polymerization reactions.
