Niaj hnub no kev lag luam roj av hauv ntiaj teb tab tom txhim kho ntau thiab nrawm dua. Nrog rau daim ntawv thov kev ua lag luam, Petroleum Resin petroleum resins tau dav siv. Niaj hnub no kuv yuav tham txog cov comonomers nyob rau hauv roj av resins muab rau koj ib tug ntau dua thiab meej kev nkag siab ntawm roj av resins.
Qhov no yog vim hais tias cov heterogeneous tertiary carbon olefins ua lub luag haujlwm hauv cov saw hloov hauv cov tshuaj tiv thaiv polymerization thiab tsim cov tertiary carbon cations ruaj khov. Nyob rau tib lub sijhawm, Petroleum Resin kuj muaj cov txiaj ntsig ntawm kev txiav tawm cov tshuaj tiv thaiv polymerization, vim tias nws yuav ntes HCl tsim los ntawm kev sib cuag ntawm AlCl3 thiab piperylene, Petroleum Resin yog li qeeb cov nyhuv catalytic ntawm HCl, Petroleum Resin thiab qhov sib npaug generates. siab molecular hnyav, tsis zoo soluble polymers.
Cov monoolefins nrog xws li kev txhim kho thiab kho kom zoo ntawm cov roj av resin yog ib co monoolefins uas muaj tertiary carbon atoms. Qhov ntau dua cov ntsiab lus ntawm cov monoolefins, Petroleum Resin qhov zoo dua solubility ntawm resin. Qhov qis dua cov ntsiab lus monoolefin, Petroleum Resin nyuaj dua cov resin thiab siab dua qhov hnyav molecular, Petroleum Resin ntau insoluble polymer Cheebtsam. Tsis tas li ntawd, cyclopentene nyob rau hauv lub luag hauj lwm zoo ib yam li cov tshuaj tsw qab hydrocarbon solvents, Petroleum Resin tuaj yeem txhawb kev tsim cov ntsiab lus siab melting thiab soluble polymer.
