Cov tsos mob: tsis muaj xim, pob tshab, tsis pub dawb- cov kua dej ntws nrog lub suab qab zib thiab ester- zoo li tsw (siab-cov pa hauv nruab nrab muaj cov tshuaj loog me me)
Kub taw tes: 100.3℃(760 mmHg); Melting point: -48 degree
Ceev: 0.940 g / cm³ (25 degree)
Flash point: Approx . 10℃(kaw khob) → Cov kua nplaum heev (GHS Flam. Liq. 2), UN 1247 PG II
Refractive index: n²⁰D ≈ 1.413
Solubility: me ntsis soluble hauv dej (kwv yees . 1.6 g / 100 mL ntawm 20 degree); miscible nrog cawv, ketones, esters, aromatic hydrocarbons, thiab chlorinated hydrocarbons; insoluble hauv glycerol thiab ethylene glycol
Polymerization nyiam: Ua rau qeeb qeeb ntawm cov polymerization ntawm chav sov; pib los ntawm lub teeb, cua sov, peroxides, los yog dawb -radical qhov chaw; industrial- cov khoom qib yuav tsum muaj cov tshuaj polymerization inhibitor (feem ntau 10–100 ppm MEHQ [p-methoxyphenol] lossis BHT)

Ib tug raug, -unsaturated ester: undergoes dawb-radical polymerization los ua PMMA (Plexiglass/acrylic); kuj ua tiav los ntawm emulsion polymerization, ncua kev kawm ntawv polymerization, thiab bulk casting.
Yuav ua tau copolymerized nrog styrene, butyl acrylate, acrylonitrile, thiab lwm yam, los kho cov iav hloov kub (homopolymer Tg ≈ 105℃).
Qhov ob daim ntawv cog lus yog raug rau cov tshuaj tiv thaiv ntxiv (hydrogenation, halogenation), thiab pawg ester tuaj yeem ua rau saponified los ua methacrylic acid.
Kev phom sij: Exothermic tus kheej -polymerization- yog tias cov polymerization inhibitor tsis ua haujlwm thiab cov cua sov dissipation tsis zoo, tawg polymerization thiab cov khoom ejection ntawm lub nruas tuaj yeem tshwm sim; Tsis txhob distilled rau dryness (vim siab -kub decomposition ntawm residual MEHQ thiab localized self-polymerization).

Cam khwb cia / Extruded PMMA: Aircraft canopies, advertising lub thawv, lub teeb qhia daim hlau, cov ntaub ntawv kho hniav
Emulsion thiab Coatings: Architectural coatings, ntawv glazing, PVC ua pab (ACR)
Copolymer: MBS (PVC cuam tshuam kev hloov pauv), MMA-styrene copolymer (pob tshab ABS lwm txoj kev), textile sizing agents
Kev kho mob: Pob txha pob txha (PMMA hlaws + BA system), cov ntaub ntawv kho hniav, cov ntaub ntawv ntshiab aligner
Electronics: Acrylate ntu rau photoresists, optical fiber cladding, tawv txheej

GHS: H225 Cov nplaim hluav taws kub heev; H302/H312 Teeb meem yog nqos los yog kov ntawm daim tawv nqaij; H315/H317/H319 Ua rau tawv nqaij khaus/tej zaum yuav ua rau tawv nqaij tsis haum/ua rau qhov muag khaus loj; H335 Tej zaum yuav ua rau ua pa ua pa.
Vapors ua rau qhov muag, qhov ntswg, thiab caj pas; high concentrations ua rau mob taub hau thiab tsaug zog. Cov kua ua rau defatting ntawm daim tawv nqaij ua rau dermatitis; Tiv tauj rau kev ua xua rau cov tib neeg rhiab heev.
Kev tuav: Siv fume hood thiab tawg- khoom pov thawj; hnav hnab looj tes nitrile thiab looj tsom iav dub. Khaws kom deb ntawm lub teeb ntawm qhov kub thiab txias (tsawg dua los yog sib npaug li 25 degree; qhov zoo tshaj 15-20 degree); khaws cov thawv ntim puv thiab nitrogen-pam. Periodically ntsuas cov ntsiab lus inhibitor; ua ib qho me me - ntsuas polymerization ua ntej siv yog tias ze rau lub sijhawm.
Cia & Thauj: Tsis txhob cia nrog peroxides, azo compounds, muaj zog acids / bases, los yog dawb -radical qhov chaw. Nyob rau hauv cov ntaub ntawv ntawm to, npog nrog ua npuas ncauj los tiv thaiv evaporation thiab nqus nrog xuab zeb los yog lub ntiaj teb; tsis txhob tso tawm rau hauv cov dej qhib ( dej toxicity).
Kev tua hluav taws: Siv cawv- ua npuas dej tiv taus, CO₂, lossis hmoov qhuav. Kev pheej hmoo ntawm tawg polymerization thiab ntim khoom tawg vim yog cua sov; Cov neeg tua hluav taws yuav tsum siv SCBA.
Ua ntej distillation / bulk polymerization: Txheeb xyuas qhov xwm txheej inhibitor (tshem tawm MEHQ ntawm NaOH ntxuav ua raws li cov kuab tshuaj ntxuav, lossis ntxiv cov inhibitor tshiab); tswj kub tsawg dua los yog sib npaug li 80 degree; tuav cov pam nitrogen; tsis txhob distilled rau dryness.
