ABSTRACT:
New curable monomeric aromatic imidodicarboxylic acid diallyl esters, such as 4-allyloxycarbonyl-N-(allyloxycarbonylmethyl)phthalimide, 1,2-ethylene bis(4-allyloxycarbonylphthalimide), or N,N'-bis(allyloxycarbonylmethyl) pyromellitimide. When heated in the presence of a free radical initiator, these monomers give cured polymers having very superior mechanical strength, thermal stability, chemical resistance and electrical properties. If this polymerization is stopped before the reaction mixture is gelled, prepolymers can be obtained. The cured polymers are especially useful as electronics materials and engineering plastics.
