1,3-DIISOPROPENYLBENZENE CAS 3748-13-8

1. Ma polima a Supramolecular amatanthawuza ma polima odziphatikiza okha ndi ma monomer ang'onoang'ono kapena ma polima ang'onoang'ono a molekyulu kudzera m'magwirizano osagwirizana. Zinthu monga pH, kutentha ndi kuwala zingayambitse kupatukana ndi kukonzanso zomangira zopanda covalent za ma polima a supramolecular, omwe amatha kusinthika. Chifukwa chake, ma polima a supramolecular ndi zida zanzeru zomwe zitha kugwiritsidwa ntchito ngati kudzichiritsa nokha komanso kudzichiritsa nokha. Chimodzi mwazochita zofufuza kunyumba ndi kunja kwazaka zaposachedwa. Ma polima a Supramolecular ali ndi ntchito zosiyanasiyana, monga zida zosinthidwa zanzeru, zida zamagetsi ndi zida zamankhwala. M'zaka zaposachedwa, kafukufuku wake wogwiritsidwa ntchito m'magawo a biological and biomedical wakula mwachangu, kuphatikiza ntchito zokhudzana ndi ma cell, uinjiniya wa minofu, ndi zina zambiri.

1,3-bis(1-methylvinyl) benzene angagwiritsidwe ntchito pokonzekera supramolecular polima motere:

Ikani 10g lipoic acid ufa mu riyakitala yokhala ndi chipangizo choyambukira, tenthetsani mafuta osamba mpaka ufa wa lipoic acid usungunuke, ndikuyamba kuyambitsa. Kenaka yikani 6g (60wt%) 1,3-bis(1-methylvinyl) benzene (DIB) mu riyakitala, ndipo pitirizani kutentha ndi kusonkhezera kwa mphindi zisanu. Kenaka yikani 0,1g ya ferric chloride acetone solution mu riyakitala, pitirizani kutentha ndi kusonkhezera kwa mphindi zitatu, siyani kutentha, ndi kuziziritsa kutentha kwa chipinda kuti mupeze supramolecular polima-1.

2.1,3-Di(1-methylvinyl) benzene angagwiritsidwe ntchito pokonzekera mtanda-kugwirizana kusinthidwa njira ya polyvinyl kolorayidi wapadera utomoni. Mphamvu ya PVC polima zakuthupi mu njira imeneyi makamaka zimadalira mankhwala kugwirizana mphamvu ndi mamolekyu pa unyolo waukulu. Udindo wa ma bond achiwiri a valence pakati pa mitundu 15 ya othandizira olumikizirana amagwiritsidwa ntchito pokonzekera ma resin apadera a PVC. Magulu ophatikizika awa ali ndi magulu ogwirira ntchito, monga ma conjugated bond, magulu a phenyl, ndi magulu a heterocyclic. Kuyambitsa maguluwa Kukhoza kuonjezera cholepheretsa chotchinga cha polymer molecular chain. Panthawi imodzimodziyo, magulu a ionic, magulu a polar kapena ma hydrogen bonds omwe amapangidwa amatha kupititsa patsogolo mphamvu ya PVC polima zakuthupi. Pogwiritsa ntchito cholumikizira cholumikizira chokhala ndi mawonekedwe enaake, zomwe zidapangidwa pano zimabweretsa mawonekedwe enaake olumikizirana mu PVC macromolecular unyolo, ndikuwusintha kuchoka pamizeremizere kupita ku netiweki yam'deralo. Kusintha kwapangidwe kumeneku kumatha kusintha kwambiri Kukana kwa kutentha kwa PVC kumatha kuchepetsa kutsika kwamafuta ndikuwongolera magwiridwe antchito ake, potero kukulitsa zochitika zogwiritsira ntchito PVC. Kupyolera mu kusinthidwa kolumikizira, ma cell a polyvinyl chloride amatha kulumikizidwa moyenerera, kotero kuti polimayo ali ndi mphamvu zambiri za polyvinyl chloride ndi zida zosinthidwa. Izi zolumikizira zolumikizira sizingagwiritsidwe ntchito polima utomoni wapamwamba kwambiri wa PVC ndi matte Amagwiritsidwa ntchito mu utomoni wa PVC. Pa nthawi yomweyi, ilinso ndi ntchito zomwe zingagwiritsidwe ntchito pakusintha kolumikizana kwa ma resins apadera a PVC, monga PVC phala utomoni, chlorine-vinyo utomoni, otsika / kopitilira muyeso polymerization digiri PVC, polyvinylidene kolorayidi, CPVC, etc.
