1,3-DIISOPROPENYLBENZENE CAS 3748-13-8

1. Mapolymer eSupramolecular anoreva mapolymer anozviunganidza ega nemamonomer madiki kana mapolymer epasi kuburikidza nekudyidzana kwezvisungo zvisina covalent. Zvinhu zvakaita sepH, tembiricha uye chiedza zvinogona kukonzera kupatsanurwa nekugadziriswazve kwezvisungo zvisina covalent zvemapolymer esupramolecular, izvo zvinodzoreredzwa. Naizvozvo, mapolymer esupramolecular zvinhu zvakangwara zvinogona kushandiswa sekuzviporesa uye kuzviporesa. Imwe yenzvimbo dzinonyanya kutsvagisa munyika nekune dzimwe nyika mumakore achangopfuura. Mapolymer eSupramolecular ane mashandisirwo akasiyana-siyana, akadai sezvinhu zvakagadziriswa, zvishandiso zvemagetsi nezvinhu zvehupenyu. Mumakore achangopfuura, tsvakiridzo yayo inoshandiswa muminda yehupenyu neya biomedical yakawedzera nekukurumidza, kusanganisira mashandisirwo ane chekuita nemasero, tissue engineering, nezvimwewo.

1,3-bis(1-methylvinyl)benzene inogona kushandiswa kugadzira supramolecular polymer seinotevera:

Isa 10g yehupfu hwe lipoic acid mu reactor ine mudziyo wekukurunga, pisa mafuta ekugeza kusvika hupfu hwe lipoic acid hwanyunguduka, wotanga kukurunga. Wobva wawedzera 6g (60wt%) 1,3-bis(1-methylvinyl)benzene (DIB) mu reactor, woramba uchidziya nekukurunga kwemaminitsi mashanu. Wobva wawedzera 0.1g ye ferric chloride acetone solution mu reactor, ramba uchidziya nekukurunga kwemaminitsi matatu, mira kudziyisa, wotonhodza kusvika patembiricha yemumba kuti uwane supramolecular polymer-1.

2.1,3-Di(1-methylvinyl)benzene inogona kushandiswa kugadzira nzira yekuchinja cross-linking ye polyvinyl chloride special resin. Simba rePVC polymer material munzira iyi rinonyanya kutsamira pa chemical bonding force nemamorekuru ari pa main chain. Basa resecondary valence bonds pakati pemhando gumi neshanu dze cross-linking agents rinoshandiswa kugadzira maPVC special resin matsva. Aya ma cross-linking agents ane mapoka chaiwo anoshanda, akadai se conjugated double bonds, phenyl groups, uye heterocyclic groups. Kuunzwa kwemapoka aya Inogona kuwedzera steric prohibition yepolymer molecular chain. Panguva imwe chete, ma ionic groups akaunzwa, polar groups kana hydrogen bonds dzakaumbwa dzinogona kuvandudza simba rePVC polymer material. Nekushandisa cross-linking agent ine chimiro chakati, chigadzirwa ichi chinounza chimiro chakati che cross-linking muPVC macromolecular chain, ichichichinja kubva pachimiro che linear kuenda pachimiro che network yemuno. Kuchinja kwechimiro ichi kunogona kuvandudza zvakanyanya. Kudzivirira kupisa kwePVC kunogona kuderedza thermal shrinkage uye kuvandudza mashandiro ayo akazara, nokudaro zvichiwedzera kuwedzera kushandiswa kwePVC. Kuburikidza nekuchinja kwekubatanidza, polyvinyl chloride molecular chain inogona kusanganiswa zvakanaka, kuitira kuti polymer ive nehunhu hwakazara hwepolyvinyl chloride nezvikamu zvakagadziriswa. Izvi zvinobatanidza hazvingogone kushandiswa chete mumaresin ePVC ane polymerization yakawanda uye matte. Inoshandiswa muPVC resin. Panguva imwe chete, inewo mukana wekushandiswa mukuchinja kwekubatanidza kwemamwe maresin ePVC, akadai sePVC paste resin, chlorine-vinegar resin, low/ultra-low polymerization degree PVC, polyvinylidene chloride, CPVC, nezvimwewo.
