Methacrylic acid, muab cov ntawv MAA, yog cov organic sib txuas. Cov tsis muaj kob uas muaj kua, nyeem roj yog carboxylic acid nrog tus ntxhiab tsw tsis hnov ​​tsw. Nws yog soluble hauv dej sov thiab miscible nrog feem ntau cov kuab tshuaj organic. Methacrylic acid yog tsim kev lag luam rau ntawm qhov loj raws li qhov ua ntej rau nws cov esters, tshwj xeeb tshaj yog methyl methacrylate (MMA) thiab poly (methyl methacrylate) (PMMA). Cov methacrylates muaj kev siv ntau, feem ntau pom tias tsim khoom lag luam polymers nrog cov npe lag luam xws li Lucite thiab Plexiglas. MAA tshwm sim me me hauv cov roj ntawm Roman chamomile.
