A method of preparing oligoestermaleinates containing isocyanuric rings by copolycondensation of 3‐(N‐2‐hydroxy‐3‐chloropropyl)isocyanurate, compound (II), and of 3‐(N‐2‐hydroxy‐3‐phenoxypropyl)isocyanurate, compound (III), with maleic anhydride alone or in mixtures with aliphatic or aromatic monocarbonic and dicarbonic acids has been developed. The copolycondensations were made with maleic anhydride, with maleic and phthalic anhydride, with maleic anhydride and adipinic acid, with maleic anhydride and oleic acid, and with maleic anhydride and stearic acid and were examined systematically. Oligoestermaleinates obtained from compound (III) have a higher temperature of dropping(dropping point) and a considerably higher thermostability than those obtained from compound (II). The oligoestermaleinates obtained from compound (II) with maleic anhydride and stearic or oleic acids are soluble in styrene and aromatic hydrocarbons; those obtained with the other substances are partially soluble in styrene. All those obtained from compound (III) are soluble in styrene. The isocyanuric oligoestermaleinates synthesized are compatible with the commercial oligoestermaleinates, such as those from ethylene glycol, diethylene glycol, and propylene glycol, and with their styrene solutions. The hardened isocyanuric oligoestermaleinates have a considerably greater thermostability than commercial oligomers hardened under the same conditions on an ethylene glycol, diethylene glycol, propylene glycol, or maleic anhydride base. The crosslinked polymers are flame‐resistant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
