(1) Copolymer o ka methyl methacrylate a me ka styrene: 372 resin, nui ka methyl methacrylate monomer.Ke liʻiliʻi ka maʻiʻo o ka monomer styrene, kokoke ka hana o ka copolymer i ka PMMA a ʻoi aku ka maʻemaʻe ma mua o PMMA.Aia kekahi hoʻomaikaʻi i ka hana, i kapa ʻia ʻo styrene-modified polymethyl methacrylate.I ka hoʻonui ʻia ʻana o ke kumu hoʻohālike i luna e x:y=15:85, ʻo ka copolymer i loaʻa he brand No. 372 resin, ʻo ia ka mea i hoʻololi ʻia i ka hoʻoheheʻe aniani organik.ʻO kekahi o nā ʻano nui o nā plastics e mālama i nā waiwai mechanical a me ka weatherability o PMMA, hoʻomaikaʻi ʻia ka hoʻoheheʻe ʻana, a hoʻemi ʻia ka hygroscopicity.
(2) Methyl methacrylate, styrene, nitrile rubber copolymer: 100 mau ʻāpana o 372 resin a me 5 mau ʻāpana o ka nitrile rubber i hui ʻia, a ua kapa ʻia ka mea hoʻohui i loaʻa he 373 resin, a hiki ke hoʻonui ʻia ka paʻakikī o kona hopena.ʻO ia kekahi o nā ʻano nui o nā mea hoʻoheheʻe no ka plexiglass i hoʻololi ʻia.
(3) Methyl methacrylate a me ka styrene, butadiene rubber copolymer: he copolymer graft o ka methyl methacrylate a me ka styrene i kālai ʻia ma ke kaulahao macromolecular o ka lāʻau butadiene.Loaʻa iā ia ka ʻōlinolino kiʻekiʻe, ke aniani kiʻekiʻe a me ka paʻakikī kiʻekiʻe, ka dyeability maikaʻi, ka transmittance kukui kiʻekiʻe a me ka pale ʻana o UV, a hiki ke hoʻohana ʻia ma ke ʻano he mea ʻike a i ʻole he mea hoʻololi i ka hopena.
