Yintoni i-SBS

I-SBS (i-styrene-butadiene-styrene) I-Poly (i-styrene-butadiene-styrene) okanye i-SBS, yirabha eqinile esetyenziselwa ukuguqula i-asphalt, ukwenza izihlangu zezihlangu, ukunyathela kwamatayara, kunye nezinye iindawo apho ukuqina kubalulekile.Luhlobo lwe-copolymer ebizwa ngokuba yi-block copolymer.Ikhonkco layo lomqolo lenziwe ngamacandelo amathathu.Eyokuqala yintambo ende ye-polystyrene, ephakathi ikhonkco elide le-polybutadiene, kwaye icandelo lokugqibela lelinye icandelo elide le-polystyrene.I-Polystyrene yiplastiki eyomeleleyo eqinile, kwaye oku kunika i-SBS ukuqina kwayo.I-Polybutadiene yirabha, kwaye oku kunika i-SBS iimpawu zayo ezifana nerabha.Ukongeza, amatyathanga e-polystyrene athande ukuhlangana kunye.Xa elinye iqela le-styrene le-molecule ye-SBS lidibanisa enye i-clump, kwaye enye ikhonkco ye-polystyrene ye-molecule ye-SBS idibanisa enye i-clump, i-clumps eyahlukileyo ibotshwa kunye ne-rubbery polybutadiene chain.Oku kunika izinto eziphathekayo amandla okugcina imilo yayo emva koluliwe
