I-polymerization eshisayo ye-petroleum resin ngokuvamile ishisa ingxenyana ye-carbon nine iye cishe ku-260°C kureactor. Okokuqala, yakha isengezo se-Diels-Alder esiphakathi kwama-molecule amabili e-polymerizable, i-Petroleum Resin bese isabela nenye i-polymerizable molecule.I-Petroleum Resin Khiqiza ama-radicals mahhala amabili, i-Petroleum Resin bese iqala ukupholisa. Indlela ye-polymerization eshisayo inenqubo elula nesivuno esikhulu, kodwa izinga lokushisa lokusabela liphezulu, ukusetshenziswa kwamandla kukhulu, ukupheka kwe-Petroleum Resin kulula, I-Petroleum Resin umbala we-resin ekhiqiziwe imnyama, futhi izinga lomkhiqizo liphansi. Isetshenziswa embonini kuphela ukukhiqiza i-resin emnyama, i-Petroleum Resin kanye nemikhiqizo yayo ikakhulukazi isetshenziselwa i-ejenti yokuqinisa i-Rubber, isengezo sikakhonkolo.
I-Catalytic polymerization ye-petroleum resins iwukusabela kwe-cationic kwe-polymerization, i-Petroleum Resin ikakhulukazi ama-monomers e-carbon ayisishiyagalolunye ngaphansi kwesenzo se-catalyst ukwakha isikhungo esisebenzayo se-carbon positive ion ukuqalisa i-polymerization ye-chain, ngaleyo ndlela kuhlanganiswe izinhlaka ze-petroleum. Isikhungo esisebenzayo sithinteka kakhulu ngezinga lokuhlukaniswa kwe-ion pair. Uma i-reaction medium ne-solvent kuhlukile, i-Petroleum Resin isikhungo esisebenzayo nayo ihlukile.I-Petroleum Resin Catalytic polymerization iyindlela yokuqala futhi esetshenziswa kabanzi ekuhlanganiseni izinhlaka ze-petroleum.
I-polymerization yamahhala ye-radical ibangelwa ukuba khona kwenani elikhulu lamabhondi angagcwele (amapheya awodwa ama-electron) ku-molecule ye-carbon enezingxenye eziyisishiyagalolunye, i-Petroleum Resin eyenza ama-radicals mahhala ngaphansi kwesenzo somuntu oqalayo futhi eqala ukupholisa kweketango. Ngemuva kokuthi umkhiqizo usuhlanganisiwe, i-Petroleum Resin ifakwe inhibitor eqinile ukuze kuqedwe ukusabela. Iziqalisi ezivame ukusetshenziswa ekwenziweni kwe-polymerization yamahhala yama-petroleum resins ama-peroxides nama-sodium fatty acids noma izingxube zawo. Inani nesilinganiso sabaqalisi kunomthelela omkhulu kukhwalithi yomkhiqizo. Umehluko oyisisekelo phakathi kwe-cationic polymerization kanye ne-free radical polymerization uhlobo oluhlukile lokuphela kweketango lokukhula, i-Petroleum Resin okungukuthi, izikhungo ezisebenzayo ezihlukene. Ukusebenza kwayo okuyinhloko kukulezi zici ezilandelayo:
Iketango lokukhula le-cationic polymerization liyashajwa;I-Petroleum Resin iketango lokukhula le-cationic polymerization kanye ne-counter ion ingabonakala kokungenhla. Ukwakheka kwengxenye ye-carbon nine kuyinkimbinkimbi, i-Petroleum Resin futhi iphuzu lokubilisa liphakeme, okunzima ukulihlukanisa ngokunembile. Icebile ngama-olefin angasetshenzisiwe, i-Petroleum Resin eyenza ingxenyenamba ye-carbon nine ilungele ukukhiqizwa. Impahla eluhlaza ye-petroleum resin.
