ʻO ke kaʻina hana hoʻomākaukau o ka resin petroleum C9 penei: ua hoʻomaʻamaʻa mua ʻia nā mea maka e wehe (bis) cyclopentadiene a me isoprene, Petroleum Resin no ka loaʻa ʻana o nā mea maka me ka hapa nui o 50%, Petroleum Resin a laila hoʻohui i kahi hydrocarbon aromatic diluent. ma lalo o ka pale o ka nitrogen, Petroleum Resin A laila e hoʻohui i ka mea hoʻoheheʻe AlCl3. E mālama i ka mahana ma 25, Petroleum Resin e hoʻohui mālie i ka piperylene a me ka comonomer, e kāohi i ka helu hānai i ʻole e ʻoi aku ka mahana o ka hopena ma mua o 40, Petroleum Resin a me ka mea paʻa i loko o ka reactor he 45% ~ 50%, a ʻo ka manawa polymerization. 1~ 2h. Ma hope o ka polymerization, hoʻouna ʻia ka Petroleum Resin i ka huahana i ka scrubber alkali. ʻO ka piko o ke kolamu ka wai polymerization decatalyzed, Petroleum Resin i hoʻouna ʻia i ka ʻōpala wai e hoʻoneʻe i ka wai alkali a me ke koena catalyst i ka wai polymerization. ʻO ka luna o ke kolamu wai e hele i ka stripper a me ka mole distillation hale kiaʻi, Distilling diluent, Petroleum Resin unpolymerized ʻāpana a me nā oligomers e kiʻi ai i ka momona molecular paona paʻa paʻa.
Hiki i ke koho ʻana i nā comonomers ʻokoʻa ke hoʻomaikaʻi i ka hana o ka resin a loaʻa i nā resins kūikawā like ʻole. No ka laʻana, hiki i ka copolymerization me ka methyl styrene ke hoʻomaikaʻi i nā waiwai adhesive o ka resin; Hiki i ka Petroleum Resin copolymerization me ka isobutylene ke loaʻa i nā resins me ka hāʻawi ʻana i ke kaumaha molekula pili; Hiki i ka Petroleum Resin copolymerization me cyclopentene ke loaʻa i nā resins me kahi kiʻekiʻe palupalu. ʻO nā comonomers maʻamau he maleic anhydride, terpenes, Petroleum Resin aromatic compounds.
