Stearyl Methacrylate CAS 32360-05-7
Stearyl Methacrylate ni ikintu cy'umweru, gifite ibara ry'umushongi kidashonga mu mazi kandi gifite impumuro y'umukara. Formula ya molekile ni C₂₂H₄₂O₂, uburemere bwa molekile ni 338.57, aho gushonga ni 18-20°C (umucyo), aho kubira ni 195°C, ubucucike ni 0.864 g/mL kuri 25°C (umucyo), umuvuduko w'umwuka ni 0.06 Pa kuri 20°C, naho igipimo cyo kugarura umwuka ni n₂₀/D = 1.451 (umucyo).

Gutunganya irangi, irangi, kole, irangi ry’imyenda n’ibikoresho byo kurangiza, irangi ry’uruhu, ibikoresho birinda amazi n’ibibuza amavuta kwinjira, ibibuza amazi kugenda, ibikoresho byo gusiga amavuta, n’ibindi bigabanya ubukana bw’amavuta mabi.
1. Imikorere ibiri: Ifite imigozi ibiri ya methacrylate hamwe n'itsinda rya alkyl rirerure rya C18, bituma habaho polymerization ya radical yigenga na copolymerization hamwe na monomers zitandukanye (nk'acrylates, styrene, acrylonitrile, nibindi) kugira ngo itange imikorere mishya kuri polymer.
2. Ubushyuhe buke bwo guhindura ikirahuri (Tg≈-100℃): Butanga ubushobozi bwo koroshya ubushyuhe buke, bukwiriye ibikoresho byagenewe ahantu hakonje.
3. Uburemere buke: Butanga ubushobozi bwo gutunganya neza iyo bukoreshejwe nk'icyuma gipima ubushyuhe, byoroshya kuvanga no gufata neza.
4. Gukomera mu binyabutabire: Birwanya hydrolysis, bigaragaza ubushyuhe buhamye, bifite aho bihurira n'ubushyuhe bugera kuri 192°C, bigatuma habaho umutekano mwiza.
