Stearyl Methacrylate CAS 32360-05-7
He totoka mā, he rite ki te ware pi te Stearyl Methacrylate, kāore e wairewa i te wai, ā, he haunga haunga. Ko tōna tauira ngota ko C₂₂H₄₂O₂, ko te taumaha ngota ko 338.57, ko te ira rewa ko 18-20°C (rita), ko te ira kohua ko 195°C, ko te mātotoru ko 0.864 g/mL i te 25°C (rita), ko te pēhanga kohu ko 0.06 Pa i te 20°C, ā, ko te taupū whakaata n₂₀/D = 1.451 (rita).

Te hanga waituhi, ngā paninga, ngā piripiri, ngā tāpiringa tae me ngā tāpiringa whakaoti kakahu, ngā tāpiringa hiako, ngā kaihoko ārai-wai me te ārai-hinu, ngā aukati rere, ngā tāpiringa hinu whakahinuhinu, me ngā whakaiti matotoru o te hinu mata.
1. Mahi-rua: Kei a ia ngā here takirua tino tauhohe o te methacrylate me te rōpū alkyl mekameka-roa C18, e āhei ai te polymerization rauropi kore utu me te copolymerization me ngā momo monomers (pērā i te acrylates, styrene, acrylonitrile, me ētahi atu) hei hoatu i ngā mahi hou ki te polymer.
2. Te pāmahana whakawhiti karāhe iti (Tg≈-100℃): He tino ngāwari ki te pāmahana iti, he pai mō ngā rauemi i hangaia mō ngā taiao makariri.
3. Matotoru iti: He pai te rere o te wai ina whakamahia hei monomer, hei āwhina i te whakaranu me te whakahaere.
4. Te pumau matū: Ātete ki te waikura, he tino pai te pumau o te wera, me te ira mura tae atu ki te 192℃, e whakarite ana i te haumaru pai.
