SBS ni iki

SBS.Nubwoko bwa copolymer bita blok copolymer.Urunigi rwumugongo rugizwe nibice bitatu.Iya mbere ni urunigi rurerure rwa polystirene, hagati ni urunigi rurerure rwa polybutadiene, naho igice cya nyuma ni ikindi gice kirekire cya polystirene.Polystirene ni plastiki ikomeye, kandi ibi biha SBS igihe kirekire.Polybutadiene ni rubbery, kandi ibi biha SBS ibintu bisa na reberi.Byongeye kandi, iminyururu ya polystirene ikunda guhurira hamwe.Iyo itsinda rimwe rya styrene ya molekile imwe ya SBS ihujwe na clump imwe, naho urundi ruhererekane rwa polystirene ya molekile imwe ya SBS ihuza irindi tsinda, uduce dutandukanye duhuzwa hamwe nu munyururu wa polybutadiene.Ibi biha ibikoresho ubushobozi bwo kugumana imiterere yabyo nyuma yo kuramburwa
