Stearyl Methacrylate CAS 32360-05-7
Stearyl Methacrylate waa cad, adag oo shamac leh oo aan ku milmin biyaha, wuxuuna leeyahay ur cad. Qaacidada molecular-ka waa C₂₂H₄₂O₂, miisaanka molecular-ku waa 338.57, dhibicda dhalaalku waa 18-20°C (iftiin), barta karkaraya waa 195°C, cufnaanta waa 0.864 g/mL 25°C (iftiin), cadaadiska uumiga waa 0.06 Pa 20°C, iyo tusmada refractive n₂₀/D = 1.451 (iftiin).

Isku-darka khad, dahaadh, dhejisyo, rinjiyeynta dharka iyo kaaliyaha dhammaystirka, kaaliyaha maqaarka, wakiilada biyaha celiya iyo kuwa ka hortaga saliidda, daawooyinka ka hortaga socodka, waxyaabaha lagu daro saliidda saliidda, iyo kuwa yareeya nuugista saliidda cayriin.
1. Shaqada laba-geesoodka ah: Waxay leedahay labadaba xidhmo laba-jibbaaran oo aad u falceliyay oo ah methacrylate iyo koox alkyl ah oo silsilad dheer leh oo C18 ah, taasoo u oggolaanaysa polymerization xagjir ah oo xor ah iyo copolymerization oo leh monomers kala duwan (sida acrylates, styrene, acrylonitrile, iwm.) si ay u siiso shaqooyin cusub polymer-ka.
2. Heerkulka kala-guurka galaaska oo hooseeya (Tg≈-100℃): Waxay bixisaa dabacsanaan heerkul hoose oo aad u fiican, oo ku habboon agabka loogu talagalay deegaannada qabow.
3. Dheecaan hooseeya: Waxay bixisaa socod wanaagsan oo farsamayn ah marka loo isticmaalo monomer ahaan, taasoo sahlaysa isku darka iyo maaraynta.
4. Xasilloonida kiimikada: Waxay u adkaysataa hydrolysis-ka, waxay muujisaa xasillooni kuleyl oo aad u fiican, iyadoo leh dhibic iftiin ah oo gaareysa 192℃, taasoo hubinaysa badbaado wanaagsan.
