I-SBS (styrene-butadiene-styrene) I-Poly (styrene-butadiene-styrene) noma i-SBS, iyirabha eqinile esetshenziselwa ukuguqula itiyela, ukwenza amathe ezicathulo, amasondo amathayi, nezinye izindawo lapho ukuqina kubalulekile.Iwuhlobo lwe-copolymer olubizwa ngokuthi i-block copolymer.Iketango layo lomgogodla lakhiwe izingxenye ezintathu.Eyokuqala iketanga elide le-polystyrene, phakathi nendawo iyiketanga elide le-polybutadiene, kanti ingxenye yokugcina ingenye ingxenye ende ye-polystyrene.I-Polystyrene iyipulasitiki eqinile eqinile, futhi lokhu kunikeza i-SBS ukuqina kwayo.I-Polybutadiene iyirabha, futhi lokhu kunikeza i-SBS izici zayo ezifana nerabha.Ngaphezu kwalokho, amaketanga e-polystyrene avame ukuhlangana ndawonye.Lapho iqembu elilodwa le-styrene le-molecule ye-SBS lijoyina i-clump eyodwa, futhi elinye iketango le-polystyrene le-molecule ye-SBS efanayo lijoyina enye i-clump, ama-clumps ahlukene aboshwa kanye namaketanga e-rubbery polybutadiene.Lokhu kunikeza impahla ikhono lokugcina isimo sayo ngemva kokwelulwa
