Abstract
Polyfunctional aziridines useful in crosslinking applications have been developed which are reaction products of (1) ethylene imine and (2) acrylates of alkoxylated trimethylol propane, neopentyl glycol, pentaerythritol, bis phenol A, bis phenol F and glycerol, each having a degree of alkoxylation of from about 2 to about 12. Examples are the bis aziridine of the diacrylate of the adduct of neopentyl glycol and 2 moles of ethylene oxide and the tris aziridine of the triacrylate of the adduct of trimethylol propane and 3 moles of ethylene oxide.
