Ngụkọta nke hydrotreat mmanụ mmanụ na Elastomer bụ ihe dị mkpa na-emetụta ike mgbapụta nke na-ekpo ọkụ gbazee amines. Tamactifier resin na Eyestomer nwere ike belata ego nke ihe nkiri colloid nke colloid, na n'okpuru nrụgide, a na-ejikọ onwe ya na ndị na-anabata ya; Ọ bụrụ na ha ekwekọghị, ego nke ihe nkiri nchekwa colloid ga-abawanye, nke ga-ebelata ndọta n'etiti colloid na nkwado.
Ndakọrịta nke iji polymer polymer na-ekwu okwu anụ ahụ metụtara polirity ya na oke molecular uka nke resin. Ọ bụrụ na polarity bụ otu ihe ahụ na oke molecular dị ka, ndakọrịta dị mma. Iji maa atụ, aromatic plasma styrene (P3) ekwekọghị na roba sọks, kama ọ dakọtara na mkparo ala na-acha uhie uhie na-emebi emebi Polyvinylcyccccccccccccluoxane (PVCH) na nkezi molecular ogo nke 650 kwekọrọ na roba eke, mana pvch na oke molecular nke 1,800 adabaghị na roba nke eke.
Bydrogenated Petrogenated Petrogenated Bind dị arọ na-arụ ọrụ, ịdị arọ molecular na-erughị 2000. Ọ bụ ihe na-eme ka ọ bụrụ ihe na-edozi ahụ . Ọ nwere nguzogide mmiri na nguzosi iche na ihu igwe.
Isi ihe ndekọ arụmọrụ ya gụnyere ebe dị nro, ụcha, na-adịghị mma, uru acid bara uru na njupụta. Isi okwu dị nro bụ ihe dị mkpa nke resin mmanụ apịtị, nke na-egosipụta ihe siri ike, onye na-efe efe na isi ike nke mmanụ ala mmanụ.
Ọnọdụ dị nro nke mmanụ yrogenated maka ụlọ ọrụ roba na-abụkarị 70 Celsius C ~ 100 Celsius resins maka ụlọ ọrụ a na-eme bụ 100 ~ 120 Celsius C. Agba bụ njiri mara ihe ọzọ dị mkpa nke mmanụ a na-eme. A na-eji agba na-acha ọkụ na ụlọ ọrụ na mkpuchi mkpuchi, a na-eji agba dị n'ime ụlọ na ụlọ ọrụ obibi akwụkwọ, a na-eji agba gbara ọchịchịrị mee ihe dị ka ihe mgbakwunye.
