Stearyl Methacrylate CAS 32360-05-7
Stearyl Methacrylate ke ntho e tšoeu, e kang boka e sa qhibiliheng metsing 'me e na le monko o bolileng. Foromo ea eona ea limolek'hule ke C₂₂H₄₂O₂, boima ba limolek'hule ke 338.57, ntlha ea ho qhibiliha ke 18-20°C (ha e le hantle), ntlha ea ho belisa ke 195°C, bongata ke 0.864 g/mL ho 25°C (ha e le hantle), khatello ea mouoane ke 0.06 Pa ho 20°C, 'me refractive index n₂₀/D = 1.451 (ha e le hantle).

Ho kopanngoa ha enke, dikoahelo, dikhomaretsi, disebediswa tsa ho daya le ho qeta tsa masela, disebediswa tsa ho thusa letlalo, dintho tse thibelang metsi le tse thibelang oli, dithibela phallo, di-additi tsa oli tse tlotsang, le disebediswa tse fokotsang viscosity ya oli e tala.
1. Tshebetso e habeli: E na le dibonto tse pedi tse arabelang haholo tsa methacrylate le sehlopha sa alkyl sa ketane e telele ya C18, e dumellang polymerization ya free radical le copolymerization ka di-monomers tse fapaneng (tse kang di-acrylates, styrene, acrylonitrile, jj.) ho fana ka mesebetsi e metjha ho polymer.
2. Mocheso o tlase oa phetoho ea khalase (Tg≈-100℃): E fana ka ho tenyetseha ho hoholo ha mocheso o tlase, ho loketse thepa e etselitsoeng libaka tse batang.
3. Ho ba le viscous e tlase: E fana ka phallo e ntle ea ts'ebetso ha e sebelisoa e le monomer, e nolofalletsang ho kopanya le ho sebetsana.
4. Botsitso ba lik'hemik'hale: E hanela hydrolysis, e bontša botsitso bo botle ba mocheso, ka ntlha ea flash e phahameng ho fihlela ho 192℃, e netefatsa polokeho e ntle.
