1,3-DIISOPROPENYLBENZENE CAS 3748-13-8

1. Polymers-ka sare waxay tilmaamayaan polymers-ka iskood isu keena oo ay sameeyaan monomers-yo yaryar oo molecular ah ama polymers-yo molecular ah oo hooseeya iyada oo loo marayo isdhexgalka isku xidhka aan covalent ahayn. Arrimaha sida pH, heerkulka iyo iftiinka waxay sababi karaan kala-goynta iyo dib-u-habaynta xidhmooyinka aan covalent ahayn ee polymers-ka sare, kuwaas oo dib loo rogi karo. Sidaa darteed, polymers-ka sare waa walxo caqli badan oo loo isticmaali karo is-bogsiin iyo is-bogsiin. Mid ka mid ah meelaha ugu daran ee cilmi-baarista ee gudaha iyo dibadda sannadihii ugu dambeeyay. Polymers-ka sare waxay leeyihiin codsiyo kala duwan, sida agabka casriga ah ee wax laga beddelay, aaladaha elektaroonigga ah iyo agabka bayoolojiga. Sannadihii ugu dambeeyay, cilmi-baaristeeda la dabaqay ee ku saabsan bayoolojiga iyo bayoolojiga ayaa si degdeg ah u horumartay, oo ay ku jiraan codsiyada la xiriira unugyada, injineernimada unugyada, iwm.

1,3-bis(1-methylvinyl)benzene waxaa loo isticmaali karaa in lagu diyaariyo polymer supramolecular ah sida soo socota:

Ku rid budada lipoic acid 10g fallaadho ku qalabaysan qalab walaaqaya, kululee weelka saliidda ilaa budada lipoic acid ay dhalaalayso, oo bilow inaad walaaqdo. Kadib ku dar 6g (60wt%) 1,3-bis(1-methylvinyl)benzene (DIB) fallaadhaha, oo sii wad kululaynta iyo walaaqidda 5 daqiiqo. Kadibna ku dar 0.1g oo ah xalka ferric chloride acetone gudaha fallaadhaha, sii wad kululaynta iyo walaaqidda 3 daqiiqo, jooji kulaylka, oo qabooji heerkulka qolka si aad u hesho polymer-1 supramolecular.

2.1,3-Di(1-methylvinyl)benzene waxaa loo isticmaali karaa in lagu diyaariyo hab wax ka beddel ah oo isku xidha resin gaar ah oo polyvinyl chloride ah. Xoogga walxaha polymer-ka PVC ee habkan wuxuu inta badan ku xiran yahay xoogga isku xidhka kiimikada iyo molecules-ka silsiladda ugu weyn. Doorka isku xidhka valentine-ka labaad ee u dhexeeya 15 nooc oo wakiillo isku xidha ayaa loo isticmaalaa in lagu diyaariyo resins gaar ah oo PVC ah. Wakiiladan isku xidha waxay ka kooban yihiin kooxo shaqo oo gaar ah, sida isku xidhka labanlaabka ah ee isku xidha, kooxaha phenyl, iyo kooxaha heterocyclic. Soo bandhigidda kooxahan Waxay kordhin kartaa caqabadda steric ee silsiladda molecular-ka polymer. Isla mar ahaantaana, kooxaha ionic ee la soo bandhigay, kooxaha polar ama isku xidhka hydrogen ee la sameeyay waxay hagaajin karaan xoogga walxaha polymer-ka PVC. Iyadoo la adeegsanayo wakiil isku xidha oo leh qaab gaar ah, ikhtiraacan hadda jira wuxuu soo bandhigayaa qaab-dhismeed isku xidha oo gaar ah silsiladda macromolecular-ka PVC, isagoo ka beddelaya qaab-dhismeed toosan una beddelaya qaab-dhismeed shabakad maxalli ah. Isbeddelkan qaab-dhismeedka ayaa si weyn u hagaajin kara Iska caabbinta kulaylka ee PVC waxay yareyn kartaa yaraanta kulaylka waxayna hagaajin kartaa waxqabadkeeda dhammaystiran, sidaas darteedna waxay sii ballaarin kartaa xaaladaha codsiga ee PVC. Iyada oo loo marayo wax ka beddelka isku xidhka, silsiladda molecular-ka polyvinyl chloride si habboon ayaa qayb ahaan loogu xidhi karaa isku xidhka, si polymer-ku u yeesho sifooyinka dhammaystiran ee polyvinyl chloride iyo qaybaha wax laga beddelay. Wakiiladan isku xidhka ah looma isticmaali karo oo keliya resins-ka PVC-ga ee polymerization-ka sare leh iyo matte. Waxaa loo isticmaalaa resin PVC. Isla mar ahaantaana, waxay sidoo kale leedahay codsiyo suurtagal ah oo ku saabsan wax ka beddelka isku xidhka ee resins-ka kale ee gaarka ah ee PVC, sida resin koollada PVC, resin-ka chlorine-khal, PVC-ga heerka polymerization-ka hooseeya/aad u hooseeya, polyvinylidene chloride, CPVC, iwm.
