Isicelo

1. Ama-polymer e-Supramolecular abhekisela kuma-polymer ahlanganiswa ngokwawo ngama-monomer amancane ama-molecule noma ama-polymer aphansi ama-molecule ngokusebenzisana kwezibopho ezingezona eze-covalent. Izici ezifana ne-pH, izinga lokushisa nokukhanya zingabangela ukuhlukana kanye nokuhlela kabusha kwezibopho ezingezona eze-covalent zama-polymer e-supramolecular, ezingaguqulwa. Ngakho-ke, ama-polymer e-supramolecular ayizinto ezihlakaniphile ezingasetshenziswa njengokuziphilisa nokuziphilisa. Enye yezindawo ezishisayo zocwaningo ekhaya nakwamanye amazwe eminyakeni yamuva nje. Ama-polymer e-Supramolecular anezinhlelo zokusebenza eziningi, njengezinto ezihlakaniphile eziguquliwe, amadivayisi kagesi kanye nezinto eziphilayo. Eminyakeni yamuva nje, ucwaningo lwayo olusetshenziswayo emikhakheni yezinto eziphilayo kanye nezokwelapha luye lwathuthuka ngokushesha, kufaka phakathi izinhlelo zokusebenza ezihlobene namaseli, ubunjiniyela bezicubu, njll.

I-1,3-bis(1-methylvinyl)benzene ingasetshenziswa ukulungiselela i-polymer ye-supramolecular kanje:

Faka u-10g we-lipoic acid powder ku-reactor efakwe idivayisi yokuxuba, fudumeza ubhavu wamafutha kuze kube yilapho u-1,3-bis(1-methylvinyl)benzene (DIB) uncibilika ku-reactor, bese uqhubeka nokushisa nokuxuba imizuzu emi-5. Bese ufaka u-0.1g wesisombululo se-ferric chloride acetone ku-reactor, qhubeka nokushisa nokuxuba imizuzu emi-3, yeka ukufudumala, bese uphola kuze kufike ekushiseni kwegumbi ukuze uthole i-supramolecular polymer-1.

I-2.1,3-Di(1-methylvinyl)benzene ingasetshenziswa ukulungiselela indlela yokuguqula ukuxhumanisa nge-cross-linking ye-polyvinyl chloride ekhethekile resin. Amandla ezinto ze-polymer ze-PVC kule ndlela ancike kakhulu emandleni okubopha amakhemikhali nama-molecule ku-chain eyinhloko. Indima yezibopho ze-valence zesibili phakathi kwezinhlobo ezingu-15 zama-agent okuxhumanisa nge-cross-linking isetshenziselwa ukulungiselela ama-resin amasha akhethekile e-PVC. Lawa ma-agent okuxhumanisa nge-cross-linking aqukethe amaqembu athile asebenzayo, njengezibopho ezimbili ezihlanganisiwe, amaqembu e-phenyl, namaqembu e-heterocyclic. Ukwethulwa kwala maqembu Kungandisa isithiyo se-steric se-polymer molecular chain. Ngesikhathi esifanayo, amaqembu e-ionic angenisiwe, amaqembu e-polar noma izibopho ze-hydrogen ezakhiwe zingathuthukisa amandla ezinto ze-polymer ze-PVC. Ngokusebenzisa i-agent yokuxhumanisa nge-cross-linking enesakhiwo esithile, lo mbono wethula isakhiwo esithile sokuxhumanisa nge-cross-linking ku-PVC macromolecular chain, usishintshe kusuka esakhiweni esiqondile siye esakhiweni senethiwekhi yendawo. Lolu shintsho lwesakhiwo lungathuthukisa kakhulu Ukumelana nokushisa kwe-PVC kunganciphisa ukuncipha kokushisa futhi kuthuthukise ukusebenza kwayo okuphelele, ngaleyo ndlela kwandise izimo zokusetshenziswa kwe-PVC. Ngokushintshashintsha kokuxhumanisa, uchungechunge lwama-molecule e-polyvinyl chloride lungaxhunyaniswa ngokufanele ngokwengxenye, ukuze i-polymer ibe nezakhiwo eziphelele ze-polyvinyl chloride kanye nezingxenye eziguquliwe. Lawa ma-ejenti okuxhumanisa angasetshenziswa kuphela kuma-resin e-PVC ane-polymerization ephezulu kanye ne-matte. Isetshenziswa kuma-resin e-PVC. Ngesikhathi esifanayo, futhi inezinhlelo zokusebenza ezingaba khona ekuguqulweni kokuxhumanisa kwamanye ama-resin akhethekile e-PVC, njenge-resin ye-PVC yokunamathisela, i-resin ye-chlorine-vinegar, i-PVC enezinga eliphansi/eliphansi kakhulu le-polymerization, i-polyvinylidene chloride, i-CPVC, njll.
