Kev hloov kho hydrogenation, C9 resin tau txais los ntawm cov tshuaj tiv thaiv polymerization feem ntau yog tsaus dua, Petroleum Resin xim av lossis xim av thermal stability tsis zoo, yog li txwv qhov kev thov, Petroleum Resin los ntawm hydrogenation tuaj yeem rhuav tshem ob daim ntawv cog lus unsaturated hauv cov resin, thiab tshem tawm cov seem. Cov khoom siv halogen, Petroleum Resin cov hloov pauv hloov tsis muaj xim thiab tsis muaj ntxhiab tsw tshwj xeeb. Nws tseem tuaj yeem txhim kho nws cov huab cua tiv thaiv, adhesion, Petroleum Resin stability thiab lwm yam khoom, thiab ntxiv nthuav nws daim ntawv thov teb. Yog li ntawd, nyob rau xyoo tas los no, cov teb chaws tsim kho tau tsom mus rau kev tsim cov roj av hydrogenated resins.
Piv nrog rau cov khoom siv raw monomer hydrogenation, cov tshuaj tiv thaiv hydrogenation ntawm roj av resin yog qhov nyuaj dua, uas yog txiav txim los ntawm cov qauv molecular ntawm roj av resin. Txij li cov roj av resins, Petroleum Resin tshwj xeeb tshaj yog muaj ntxhiab hydrocarbon resins nrog benzene rings, muaj qhov hnyav molecular hnyav, Petroleum Resin polymer molecules stretch on the catalyst deg, Petroleum Resin forming high steric hindrance, which makes the reaction condition harsh. Kev tsim cov txheej txheem tsim thiab kev ua haujlwm ntawm hydrogenated roj av resin txawv teb chaws yog nruj dua. Raws li qhov sib txawv ntau lawm thiab cov khoom yuav tsum tau, Petroleum Resin cov txheej txheem tuaj yeem muab faib ua peb hom: slurry xeev, taag txaj, Petroleum Resin tsuag ntauwd hydrogenation txheej txheem.
Kev hloov pauv copolymerization, graft copolymerization yog ib txoj hauv kev tseem ceeb ntawm kev hloov pauv tshuaj polymer. Kev tshawb fawb ntawm graft polymer cov ntaub ntawv feem ntau suav nrog ob qho kev qhia, Petroleum Resin ib qho yog kev kawm ntawm graft polymer khoom nws tus kheej, thiab lwm yam yog kev tshawb fawb ntawm cov graft polymer ua ib qho kev sib tw los txhim kho kev sib raug zoo. Tus qub yog los soj ntsuam cov qauv molecular, Roj av Resin txuas polymers nrog ntau yam tshwj xeeb cov khoom los ntawm cov tshuaj bonds, thiab tsim ib tug heev complex khoom, Petroleum Resin lub thiaj li hu ua polymer molecular tsim. Lub grafted polymer tuaj yeem tsim ib qho microstructure ntawm txhua yam, yog li Raws li ntau lub zog ntawm cov saw hlau tseem ceeb thiab cov saw hlau polymer, Roj av Resin tuaj yeem muab kev ua si tag nrho rau nws cov yam ntxwv sib xyaw; tom kawg yog siv lub peev xwm compatibilizing ntawm graft polymer raws li ib tug compatibilizer, Petroleum Resin thiaj li ywj siab tswj cov polymer sib xyaw Compatibility, uas yog, graft polymer raws li ib tug compatibilizer rau molecular tsim, Petroleum Resinpreparation ntawm polymer cov ntaub ntawv. C9 roj av resin yog soluble nyob rau hauv ntau yam organic solvents xws li alkanes, Petroleum Resin aromatic hydrocarbons, esters, Petroleum Resin thiab lwm yam. C9 roj av resin muaj zog compatibility.
