ỤDỊ:
Maleic Anhydride (MAN) bụ ihe mejupụtara organic nwere usoro kemịkalụ C4H203. Ọ bụ acid anhydride nke maleic acid ma n'ọnọdụ ya dị ọcha, ọ bụ ihe siri ike na-enweghị agba ma ọ bụ ọcha nwere isi ọjọọ. Maleic anhydride bụ molekul pụrụ iche n'ezie n'ihi na o nwere ụdị ọrụ kemịkalụ abụọ, nke na-eme ka ọ baa uru nke ukwuu na mmepụta kemịkalụ na ojiji ya.
Maleic Anhydride bụ ihe eji arụ ọrụ kemịkalụ dị iche iche, nke a na-eji eme ihe n'ọtụtụ ngalaba nke ụlọ ọrụ kemịkalụ. Ojiji ya bụ isi ihe eji eme ihe n'imepụta resin polyester na-enweghị afọ ojuju (UPR).
A na-eji resin ndị a eme ihe ma n'ime ihe eji iko eme ihe ma n'ime ihe eji eme ihe na-enweghị ihe mgbochi. Ojiji UPR gụnyere ọtụtụ ojiji n'ihe owuwu, ụlọ ọrụ mmiri na ụgbọ ala.
