Isicelo

1. Iipolymers ze-Supramolecular zibhekisa kwiipolymers ezizihlanganisele ngokwazo ziimonomers ezincinci zemolekyuli okanye iipolymers zemolekyuli ephantsi ngokusebenzisa i-non-covalent bond interactions. Izinto ezinje nge-pH, ubushushu kunye nokukhanya kunokubangela ukuqhawuka kunye nohlengahlengiso lweebhondi ezingezizo ezi-covalent zeepolymers ze-supramolecular, ezibuyiselwa umva. Ke ngoko, iipolymers ze-supramolecular zizinto ezikrelekrele ezinokuthi zisetyenziswe njengokuziphilisa kunye nokuziphilisa. Enye yeendawo zophando ezithandwayo ekhaya naphesheya kwiminyaka yakutshanje. Iipolymers ze-Supramolecular zinoluhlu olubanzi lwezicelo, ezifana nezixhobo zobuchule ezilungisiweyo, izixhobo zombane kunye nezixhobo zebhayoloji. Kwiminyaka yakutshanje, uphando lwayo olusetyenzisiweyo kwiinkalo zebhayoloji kunye ne-biomedical luphuhliswe ngokukhawuleza, kubandakanywa izicelo ezinxulumene neeseli, ubunjineli bezicubu, njl.

I-1,3-bis(1-methylvinyl)benzene ingasetyenziselwa ukulungisa i-polymer ye-supramolecular ngolu hlobo lulandelayo:

Beka i-10g ye-lipoic acid powder kwi-reactor exhotywe ngesixhobo sokuvuselela, ukutshisa i-oyile yokuhlamba i-oyile de i-lipoic acid powder inyibilike, kwaye uqale ukuphazamisa. Emva koko yongeza i-6g (60wt%) 1,3-bis (1-methylvinyl)benzene (DIB) kwi-reactor, kwaye uqhubeke ufudumeza kwaye uvuselele imizuzu emi-5. Emva koko yongeza i-0.1g yesisombululo se-acetone ye-acetone kwi-reactor, qhubeka ufudumeza kwaye uvuselele imizuzu emi-3, yeka ukufudumeza, kwaye uphole kwiqondo lobushushu begumbi ukufumana i-supramolecular polymer-1.

I-2.1,3-Di (1-methylvinyl) ibenzene ingasetyenziselwa ukulungiselela indlela yokuguqulwa kwe-cross-linking ye-polyvinyl chloride ye-resin ekhethekileyo. Amandla ezinto PVC polymer kule ndlela ikakhulu kuxhomekeke amandla bonding imichiza kunye iimolekyuli kwikhonkco eliphambili. Indima yeebhondi zesibini ze-valence phakathi kweentlobo ze-15 ze-cross-linking agents zisetyenziselwa ukulungisa ii-resin ezikhethekileyo ze-PVC. Ezi arhente ezinqamlezayo ziqulethe amaqela athile asebenzayo, afana ne-conjugated double bonds, amaqela e-phenyl, kunye namaqela e-heterocyclic. Ukuqaliswa kwala maqela Kunokwandisa umqobo we-steric we-polymer molecular chain. Ngelo xesha, amaqela e-ionic aziswayo, amaqela e-polar okanye iibhondi ze-hydrogen ezenziweyo zinokuphucula amandla e-PVC polymer material. Ngokusebenzisa i-agent edibeneyo kunye nesakhiwo esithile, ukuveliswa kwangoku kwazisa isakhiwo esithile sokudibanisa kwi-PVC macromolecular chain, sitshintshe ukusuka kwisakhiwo somgca ukuya kwisakhiwo senethiwekhi yendawo. Olu tshintsho lwesakhiwo lunokuphucula kakhulu Ukumelana nobushushu kwePVC kunokunciphisa ukucutha kwe-thermal kunye nokuphucula ukusebenza kwayo okubanzi, ngaloo ndlela ukwandisa ngakumbi iimeko zesicelo sePVC. Ngokusebenzisa ukuguqulwa kwe-cross-linking, i-polyvinyl chloride ye-molecular chain inokuthi idibaniswe ngokufanelekileyo ngokufanelekileyo, ukwenzela ukuba i-polymer ineempawu ezibanzi ze-polyvinyl chloride kunye namacandelo aguqulwayo. Ezi arhente ezinqamlezayo azinakusetyenziswa kuphela kwi-polymerization ephezulu ye-PVC resins kunye ne-matte Isetyenziswe kwi-resin ye-PVC. Kwangaxeshanye, ikwanazo izicelo ezinokuthi zibekho kwi-cross-linking modification yezinye iiresin ezikhethekileyo zePVC, ezifana ne-PVC paste resin, i-chlorine-vinegar resin, i-low/ultra-low polymerization degree PVC, i-polyvinylidene chloride, i-CPVC, njl.
