Hana ʻia nā ʻīnika, nā uhi ʻana, nā mea hoʻopili, nā mea hoʻoluʻu lole a me nā mea kōkua hoʻopau, nā mea kōkua ʻili, nā mea pale wai a me nā mea pale ʻaila, nā mea kāohi kahe, nā mea hoʻohui ʻaila lubricating, a me nā mea hoʻēmi i ka mānoanoa o ka ʻaila maka.
1. Hana pālua: Loaʻa iā ia nā pilina pālua pane nui o ka methacrylate a me kahi hui alkyl kaulahao lōʻihi C18, e ʻae ana i ka polymerization radical manuahi a me ka copolymerization me nā monomers like ʻole (e like me acrylates, styrene, acrylonitrile, etc.) e hāʻawi i nā hana hou i ka polymer.
2. Haʻahaʻa ka mahana hoʻololi aniani (Tg≈-100 ℃): Hāʻawi i ka maʻalahi o ka mahana haʻahaʻa maikaʻi loa, kūpono no nā mea i hoʻolālā ʻia no nā wahi anuanu.
3. ʻO ka mānoanoa haʻahaʻa: Hāʻawi i ke kahe hana maikaʻi ke hoʻohana ʻia ma ke ʻano he monomer, e hoʻomaʻalahi ana i ka hui ʻana a me ka lawelawe ʻana.
4. Paʻa kemika: Kūpaʻa i ka hydrolysis, hōʻike i ke kūpaʻa wela maikaʻi loa, me kahi kiko flash e like me 192 ℃, e hōʻoiaʻiʻo ana i ka palekana maikaʻi.
