4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) ke motsoako oa lintho tse phelang. Ke phofo e tšoeu ea kristale e nang le botsitso bo phahameng ba mocheso le ho hanyetsa boemo ba leholimo.
Motsoako o ka sebelisoa ho lokisa lisebelisoa tsa polyester tse phahameng tse nang le khanyetso e phahameng ea oxidation le ho hanyetsa mocheso, 'me e na le mefuta e mengata ea likopo. E ka sebelisoa e le mofetoleli ho ntlafatsa thepa ea thepa ea polyester, joalo ka ductility, matla le ho hanyetsa boemo ba leholimo. E ka boela ea sebelisoa e le fotosensitizer le tlatsetso bakeng sa li-catalysts tsa polymerization.
Mokhoa oa ho lokisa 4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid) o rarahane 'me o hloka ho fumanoa ka mehato e mengata. Mokhoa o sebelisoang hangata ke ho arabela phthalic acid le methylene trifluoride tlas'a maemo a alkaline ho fana ka 4,4′-(2,2,2-trifluoro-1-trifluoromethyl)ethylenebis(1,2-benzenedicarboxylic acid).
Tlhahisoleseding ea polokeho: Mekhoa e nepahetseng ea ho sebetsana le litemoso li lokela ho nkoa nakong ea ho lokisoa le ho sebelisoa ha motsoako ona. E na le chefo e itseng le ho teneha, 'me e lokela ho qojoa ho hema lerōle le ho kopana le letlalo, mahlo, joalo-joalo. Apara liatlana tse sireletsang, limaske le likhalase ho netefatsa hore ho na le moea o motle nakong ea ts'ebetso.
