heal.abstract	Hot-setting epoxy systems, consisting of a bisphenol A diglycidyl ether resin cured with phthalic anhydride and dibutyl phthalate as plasticizing agent (mainly for photoelastic applications), exhibit crazing phenomena when processed at moderately high temperatures. Chemical analysis and i.r. spectroscopy reveal that crazing is due to rejection of dibutyl phthalate from the surface layers of the specimens. The same phenomenon appears with triethylenetetramine (TETA)-cured cold-setting systems, where dibutyl phthalate undergoes transamidification with TETA before rejection. © 1974.	en
