ETHYLENE GLYCOL BIS(4-TRIMELLITATE ANHYDRIDE) CAS:1732-96-3

"Ethylene Glycol Bis (4-trimellitate anhydride), eo hangata e bitsoang EGTMAC, ke motsoako oa lik'hemik'hale o sebetsang ka bongata o nang le lits'ebetso tse fapaneng liindastering tse fapaneng. E 'ngoe ea ts'ebeliso ea eona ea mantlha e lefapheng la mahlale a polymer. EGTMAC e sebetsa e le moemeli oa bohlokoa oa ho hokahanya le monomer tlhahisong ea li-polymer le li-resin tse sebetsang hantle. Li-polymer tsena li bontša botsitso bo ikhethang ba mocheso, matla a mechini, le ho hanyetsa lik'hemik'hale le li-solvents. Ho kenyelletsoa ha EGTMAC ho ntlafatsa ts'ebetso le ho tšoarella ha matrices a polymer a hlahisoang, ho etsa hore a lokele ts'ebeliso ea li-coatings, likhomaretsi le lisebelisoa tse kopaneng. Ho feta moo, EGTMAC e bapala karolo ea bohlokoa k'hemistri ea thepa. Lihlopha tsa eona tsa anhydride li e nolofalletsa ho arabela le metsoako e fapaneng, e leng se lebisang ho thehoeng ha lisebelisoa tse sebetsang joalo ka li-resin tsa thermosetting, li-additives tse thibelang mollo, le li-coat tse thibelang mocheso. Lisebelisoa tsena li fumana lits'ebetso liindastering tse hlokang botsitso ba mocheso o phahameng, ho lieha ha mollo, le ho hanyetsa mafome, ho kenyeletsoa le mafapha a lifofane, likoloi le kaho. Ho feta moo, EGTMAC e sebelisoa haholo ho organic synthesis. Reactation ea eona e lumella ts'ebetso ea li-polymer, li-oligomer, le limolek'hule tse nyane, e leng se lebisang nts'etsopele ea lik'hemik'hale tse ikhethang, li-plasticizer le li-additives tsa lubricant. Bafuputsi ba sebelisa EGTMAC e le sesebelisoa sa bohlokoa sa ho kopanya metsoako e rarahaneng ea lintho tse phelang e nang le thepa e etselitsoeng lits'ebetso tse itseng tsa indasteri le tsa khoebo. Ho feta moo, motsoako ona o fumana thuso lefapheng la phetoho ea bokaholimo le ho khothaletsa ho khomarela. Bokhoni ba eona ba ho theha likhokahano tse tšoarellang tsa covalent le li-substrate tse fapaneng bo etsa hore e lokele ho fetola bokaholimo le ho ntlafatsa ho khomarela pakeng tsa lisebelisoa tse fapaneng. Li-promoter tsa ho khomarela tse thehiloeng ho EGTMAC li sebelisoa ho koaheleng, enkeng le likhomaretsi ho ntlafatsa matla a ho kopanya le botsitso ba nako e telele. Ka bokhutšoanyane, Ethylene Glycol Bis (4-trimellitate anhydride), kapa EGTMAC, e na le lits'ebetso tsa bohlokoa saenseng ea polymer, k'hemistri ea lisebelisoa, tlhahiso ea lintho tse phelang, le phetoho ea bokaholimo. Sebopeho sa eona se ikhethang sa anhydride le reactivity e feto-fetohang li etsa hore e be motsoako oa bohlokoa bakeng sa ho nts'etsapele li-polymer tse sebetsang hantle, lisebelisoa tse sebetsang, limolek'hule tse rarahaneng tsa lintho tse phelang, le li-promoter tsa ho khomarela. Mefuta e fapaneng ea lits'ebetso e etsa hore EGTMAC e be karolo ea bohlokoa ho ntšetseng pele tsoelo-pele ea theknoloji le lipatlisiso tsa mahlale.
