Polymerization Control Reaction Ntawm Trithiocarbonate
Oct 27, 2021
Nyob rau hauv xyoo tas los no, txoj kev loj hlob ntawm kev ua neej nyob polymerization tau muab ib txoj hauv kev zoo rau kev tsim cov polymers ntawm ntau yam qauv. Ntxiv trithiocarbonate rau hauv cov txheej txheem polymerization tuaj yeem tswj tau cov tshuaj tiv thaiv polymerization thiab tuaj yeem npaj cov polymers nrog cov qauv tshwj xeeb.
Trithiocarbonate yog siv rau kev tswj cov dawb radical polymerization, tshwj xeeb tshaj yog tsim rau cov saw hloov chaw (CTA) rau cov polymerization ntawm styrene, acrylate thiab acrylamide monomers. Trithiocarbonate muaj cov qauv ntawm alkane ntev C12H25 thiab dimethyl acetic acid. Nws yog dav siv nyob rau hauv lub synthesis ntawm cov khoom lom nyob rau hauv lub cev. Nws ua lub luag haujlwm hauv kev tswj qhov hnyav molecular ntawm polymerization hauv cov tshuaj tiv thaiv polymerization. Nws muaj ntau yam siv tau monomers thiab kev ua haujlwm me me. Thiab cov khoom molecular hnyav yog tswj tau ntau dua.
Piv nrog dithiobenzoate RAFT saw hloov cov neeg sawv cev, trithioester RAFT polymerization yog ib txoj hauv kev zoo heev rau kev ua haujlwm ntawm qhov kawg ntawm cov polymer. Los ntawm kev kho qhov piv ntawm trithioester RAFT reagent/initiator/monomer Proportion, koj tuaj yeem tau txais ntau qib ntawm polymerization.
