Poly (ethyl vinyl ether) Siv Thiab Synthesis

Chemical Properties	Poly (ethyl vinyl ether) yog opaque amber viscous kua, Nws yog cov khoom siv hydrophobic uas yog insoluble hauv dej los yog lwm yam polar solvents.
Siv	Poly (ethyl vinyl ether) tuaj yeem siv los ua plasticiser rau cellulose nitrate thiab cellulose resin lacquers, ua lub hauv paus rau cov nplaum nplaum rau hauv cov yeeb yaj kiab thiab cov ntaub nplaum, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov phais. Kuj tseem siv rau kev phais phais uas tsis yog khaus khaus uas yuav tsum tau muaj dej permeability thiab ua kom qhuav-zaj duab xis yooj yooj yim thiab nce viscosity ntawm photochemical resist-coating compositions.
Kev npaj	Rau lub raj mis uas muaj 200 gm ntawm benzene ntxiv 1.0 gm ntawm txhuas chloride. Qhov sib tov yog nplawm kom tshem tawm cov catalyst thiab tom qab ntawd maj mam ntxiv ntawm 200 gm (2.78 moles) ntawm vinyl ether pib. Cov tshuaj tiv thaiv yog exothermic, thiab thaum kub nce mus rau 60 degree -80 degree qhov ntxiv yog qeeb kom tsuas yog 1-2 gm ntawm vinyl ethyl ether ntxiv rau ib zaug. Polymerization yog kuaj pom los ntawm qhov pib ntawm turbidity thiab xim av me ntsis. Thaum cov xim xim av ploj mus, qhov ntxiv ntxiv ntawm vinyl ethyl ether ntxiv. Tom qab ua tiav qhov sib ntxiv cov tshuaj tiv thaiv yog rhuab mus rau 80 degree. Cov benzene thiab volatiles yog chav-distilled tawm, thiab cov seem seem yog kwv yees li 144 gm (72%) ntawm cov khoom daj balsamlike. Kev npaj ntawm Poly (vinyl ethyl ether) Siv Aluminium Chloride Catalyst
Hazard	Muaj tshuaj lom.
Kev ruaj ntseg Profile	Muaj tshuaj lom los ntawm txoj kev intraperitoneal. Thaum rhuab mus rau decomposition nws emissions pa luam yeeb thiab irritating vapors.
