Posachedwapa, chinthu chatsopano, poly(methyl vinyl ether – alt – maleic anhydride), chomwe chikuwonetsa kuthekera kwakukulu kogwiritsidwa ntchito m'magawo osiyanasiyana, chakopa chidwi cha anthu ambiri.
Poly (methyl vinyl ether – alt – maleic anhydride) ndi polima wopangidwa ndi kulumikizana kwa ma monomers awiri, methyl vinyl ether ndi maleic anhydride. Chifukwa cha kapangidwe kake ka mankhwala, ili ndi zinthu zosiyanasiyana zabwino, monga kusungunuka bwino kwa madzi, kuyanjana ndi zinthu zina, komanso kuyankha kwa pH. Chifukwa chake, imagwiritsidwa ntchito m'magawo ambiri, kuphatikizapo mankhwala, zodzoladzola, zokutira, kupanga mapepala, ndi mankhwala amafuta.

Mu makampani opanga mapepala, poly(methyl vinyl ether – alt – maleic anhydride) ingagwiritsidwe ntchito ngati chowonjezera kukula kuti ipange filimu yoteteza pamwamba pa pepala, kuchepetsa kuyamwa kwa madzi a pepala ndikuwonjezera magwiridwe antchito ake osagwira madzi. Imagwiritsidwa ntchito kwambiri popanga mapepala opaka, mapepala olembera, ndi zina zotero. Nthawi yomweyo, ingagwiritsidwe ntchito ngati chowonjezera mphamvu, cholumikizana ndi ulusi wa pepala kuti chiwonjezere mphamvu yomangirira pakati pa ulusi ndikuwonjezera mphamvu ya pepala, monga mphamvu yokoka ndi mphamvu yong'ambika.
Mu mankhwala ophera mafuta, copolymer iyi ingagwiritsidwe ntchito ngati chowonjezera cha madzi obowola kuti isinthe momwe madzi obowola amagwirira ntchito, kupanga keke yosefera pakhoma la chitsime, kuwongolera kutayika kwa madzi, kukhazikika pakhoma la chitsime, kupewa kugwa kwa mapangidwe, ndikuwonetsetsa kuti ntchito zobowola zikuyenda bwino. Kuphatikiza apo, ingagwiritsidwe ntchito ngati chothandizira kuchotsa mafuta. Pambuyo pobayidwa mu chosungira mafuta, posintha mphamvu ya mafuta pakati pa madzi, imapangitsa mafuta osaphika kukhala osavuta kuchotsedwa m'mabowo a miyala, ndikuwonjezera kuchuluka kwa mafuta osaphika.
