1,3-DIISOPROPENYLBENZENE CAS 3748-13-8

1. Ma polima a Supramolecular amatanthauza ma polima omwe amasonkhana okha ndi ma monomers ang'onoang'ono a ma molekyulu kapena ma polima otsika a ma molekyulu kudzera mu mgwirizano wosalumikizana ndi ma bond. Zinthu monga pH, kutentha ndi kuwala zingayambitse kugawikana ndi kukonzanso ma bond osalumikizana a ma polima a supramolecular, omwe amatha kusinthika. Chifukwa chake, ma polima a supramolecular ndi zinthu zanzeru zomwe zingagwiritsidwe ntchito ngati kudzichiritsa komanso kudzichiritsa. Limodzi mwa malo ofufuzira kwambiri kunyumba ndi kunja kwa dziko m'zaka zaposachedwa. Ma polima a Supramolecular ali ndi ntchito zosiyanasiyana, monga zipangizo zanzeru zosinthidwa, zida zamagetsi ndi zinthu zamoyo. M'zaka zaposachedwa, kafukufuku wake wogwiritsidwa ntchito m'magawo a zamoyo ndi zamankhwala wakula mofulumira, kuphatikizapo ntchito zokhudzana ndi maselo, uinjiniya wa minofu, ndi zina zotero.

1,3-bis(1-methylvinyl)benzene ingagwiritsidwe ntchito pokonza polima ya supramolecular motere:

Ikani ufa wa 10g wa lipoic acid mu reactor yokhala ndi chipangizo chosakaniza, tenthetsani bafa la mafuta mpaka ufa wa lipoic acid utasungunuka, ndipo yambani kusakaniza. Kenako onjezerani 6g (60wt%) 1,3-bis(1-methylvinyl)benzene (DIB) mu reactor, ndipo pitirizani kutenthetsa ndi kusakaniza kwa mphindi 5. Kenako onjezerani 0.1g ya ferric chloride acetone solution mu reactor, pitirizani kutenthetsa ndi kusakaniza kwa mphindi 3, siyani kutenthetsa, ndipo muziziziritse kutentha kwa chipinda kuti mupeze supramolecular polymer-1.

2.1,3-Di(1-methylvinyl)benzene ingagwiritsidwe ntchito kukonzekera njira yosinthira yolumikizirana ya polyvinyl chloride special resin. Mphamvu ya zinthu za polymer za PVC munjira iyi imadalira kwambiri mphamvu yolumikizirana ndi mamolekyu a mankhwala pa unyolo waukulu. Ntchito ya ma valence bond achiwiri pakati pa mitundu 15 ya ma cross-linking agents imagwiritsidwa ntchito kukonzekera ma resin atsopano apadera a PVC. Ma cross-linking agents awa ali ndi magulu enaake ogwira ntchito, monga ma conjugated double bonds, ma phenyl groups, ndi ma heterocyclic groups. Kuyambitsa magulu awa Kungawonjezere choletsa cha steric cha unyolo wa polymer molecular. Nthawi yomweyo, magulu a ionic omwe adayambitsidwa, magulu a polar kapena ma hydrogen bonds omwe adapangidwa amatha kupititsa patsogolo mphamvu ya zinthu za polymer za PVC. Pogwiritsa ntchito cross-linking agent yokhala ndi kapangidwe kake, izi zimabweretsa kapangidwe kake ka cross-linking mu unyolo wa macromolecular wa PVC, ndikuwusintha kuchokera ku kapangidwe ka linear kupita ku kapangidwe ka netiweki yakomweko. Kusintha kwa kapangidwe kameneka kumatha kusintha kwambiri Kukana kutentha kwa PVC kumatha kuchepetsa kuchepa kwa kutentha ndikuwonjezera magwiridwe ake onse, motero kukulitsa kwambiri zochitika zogwiritsira ntchito PVC. Kudzera mu kusintha kwa ma cross-linking, unyolo wa mamolekyulu a polyvinyl chloride ukhoza kulumikizidwa bwino pang'ono, kotero kuti polimayo ili ndi mphamvu zonse za polyvinyl chloride ndi zinthu zosinthidwa. Zogwirizanitsa izi sizingagwiritsidwe ntchito kokha mu ma resin a PVC okhala ndi polymerization yapamwamba komanso matte. Zimagwiritsidwanso ntchito mu PVC resin. Nthawi yomweyo, ilinso ndi ntchito zomwe zingatheke mu kusintha kwa ma resin ena apadera a PVC, monga PVC paste resin, chlorine-viniga resin, low/ultra-low polymerization degree PVC, polyvinylidene chloride, CPVC, ndi zina zotero.
