1,3-DIISOPROPENYLBENZENE CAS 3748-13-8

1. Polymer Supramolecular na-ezo aka na polima ndị obere monomers molekul ma ọ bụ polima molekul dị ala jikọtara onwe ha site na mmekọrịta njikọ na-abụghị covalent. Ihe ndị dị ka pH, okpomọkụ na ìhè nwere ike ibute nkewa na nhazigharị nke njikọ na-abụghị covalent nke polima supramolecular, nke a na-agbanwe agbanwe. Ya mere, polima supramolecular bụ ihe amamihe dị na ya nke enwere ike iji dị ka ọgwụgwọ onwe onye na ọgwụgwọ onwe onye. Otu n'ime ebe nchọpụta na-aga n'ihu n'ụlọ na mba ofesi n'afọ ndị na-adịbeghị anya. Polima Supramolecular nwere ọtụtụ ngwa, dị ka ihe smart gbanwere, ngwaọrụ eletrọnịkị na ihe bayoloji. N'afọ ndị na-adịbeghị anya, nyocha ya etinyere na ngalaba bayoloji na biomedical etolitela ngwa ngwa, gụnyere ngwa metụtara sel, injinia anụ ahụ, wdg.

Enwere ike iji 1,3-bis(1-methylvinyl)benzene kwadebe polima supramolecular dị ka ndị a:

Tinye ntụ ntụ lipoic acid 10g n'ime ihe e ji agwakọta ihe, kpoo mmanụ ahụ ruo mgbe ntụ ntụ lipoic acid ga-agbaze, wee malite ịkpalite ya. Tinye 6g (60wt%) 1,3-bis(1-methylvinyl)benzene (DIB) n'ime ihe e ji agwakọta ihe, wee nọgide na-ekpo ọkụ ma na-akpali ya ruo nkeji ise. Tinye 0.1g nke ihe ngwọta ferric chloride acetone n'ime ihe e ji agwakọta ihe, gaa n'ihu na-ekpo ọkụ ma na-akpali ya ruo nkeji atọ, kwụsị ikpo ọkụ, ma jụọ oyi ruo n'ọkwa ụlọ iji nweta supramolecular polymer-1.

Enwere ike iji 2.1,3-Di(1-methylvinyl)benzene kwadebe usoro mgbanwe njikọta nke resin pụrụ iche nke polyvinyl chloride. Ike nke ihe polymer PVC na usoro a dabere na ike njikọ kemịkalụ na molekul dị na agbụ isi. Ọrụ nke njikọ valence nke abụọ n'etiti ụdị ihe njikọta 15 dị iche iche iji kwadebe resin pụrụ iche PVC ọhụrụ. Ndị na-ejikọ njikọ ndị a nwere otu ọrụ pụrụ iche, dị ka njikọ abụọ ejikọtara, otu phenyl, na otu heterocyclic. Ntinye nke otu ndị a Ọ nwere ike ịbawanye mgbochi steric nke yinye molekul polymer. N'otu oge ahụ, otu ionic ewebatara, otu polar ma ọ bụ njikọ hydrogen nke e guzobere nwere ike ime ka ike nke ihe polymer PVC ka mma. Site na iji ihe na-ejikọ njikọ nwere otu nhazi, ihe mepụtara a na-ewebata usoro njikọ njikọta kpọmkwem n'ime yinye macromolecular PVC, na-agbanwe ya site na nhazi ahịrị gaa na nhazi netwọk mpaghara. Mgbanwe nhazi a nwere ike ime ka ọ ka mma nke ukwuu Nguzogide okpomọkụ nke PVC nwere ike ibelata mbelata okpomọkụ ma melite arụmọrụ zuru oke ya, si otú a na-agbasa ọnọdụ ngwa nke PVC. Site na mgbanwe njikọta, a pụrụ ijikọta usoro molekul polyvinyl chloride nke ọma, nke mere na polima ahụ nwere ihe ndị zuru oke nke polyvinyl chloride na ihe ndị agbanwere agbanwe. A naghị eji ihe ndị a na-ejikọ cross-link naanị na PVC resins na matte dị elu. A na-eji ya na PVC resin. N'otu oge ahụ, ọ nwekwara ike itinye ya na mgbanwe njikọta cross-link nke resins pụrụ iche PVC ndị ọzọ, dịka PVC paste resin, chlorine-vinegar resin, PVC dị ala/ultra-low polymerization degree, polyvinylidene chloride, CPVC, wdg.
