Usoro nkwadebe nke C9 petroleum resin bụ nke a: a na-emezi ngwa ngwa iji wepụ (bis) cyclopentadiene na isoprene, mmanụ mmanụ iji nweta akụrụngwa nke nwere akụkụ dị nta karịa 50%, mmanụ mmanụ ma tinyezie hydrocarbon aromatic diluent. n'okpuru nchebe nke nitrogen, Petroleum resin wee tinye ihe na-akpali akpali AlCl3. Debe okpomọkụ na 25, petroleum resin jiri nwayọọ nwayọọ tinye piperylene na comomer, na-achịkwa ọnụego nri ka mmeghachi omume okpomọkụ ghara gafere 40, mmanụ mmanụ na ihe siri ike na reactor bụ 45% ~ 50%, na oge polymerization bụ. 1 ~ 2h. Mgbe polymerization gasịrị, a na-ezigara mmanụ mmanụ mmanụ na alkali scrubber. N'elu kọlụm bụ mmiri mmiri polymerization decatalyzed, mmanụ mmanụ nke a na-ezigara na mmiri na-ehichapụ mmiri iji wepụ mmiri mmiri alkali na ihe fọdụrụ na mmiri polymerization. N'elu kọlụm mmiri na-aga na stripper na agụụ distillation tower , Distilling diluent, Petroleum Resin unpolymerized components na oligomers iji nweta elu molekụla arọ siri ike petroleum lining griiz.
Ịhọrọ comonomers dị iche iche nwere ike imeziwanye arụmọrụ nke resin ma nweta resins pụrụ iche dị iche iche. Dị ka ihe atụ, copolymerization na methyl styrene nwere ike imeziwanye nrapado Njirimara nke resin; Petroleum Resin copolymerization na isobutylene nwere ike nweta resins na warara ikwu arọ nkesa molekul; Petroleum resin copolymerization na cyclopentene nwere ike nweta resins na elu nro nro. Comonomers a na-ejikarị eme ihe bụ maleic anhydride, terpenes, petroleum resin aromatic ogige.
