Block copolymer yog ib qho tshwj xeeb polymer npaj los ntawm kev sib txuas ob lossis ntau qhov polymer ntu nrog cov khoom sib txawv.
Block polymers nrog cov qauv tshwj xeeb yuav qhia cov khoom sib txawv los ntawm cov khoom siv yooj yim linear polymers, nrog rau ntau cov copolymer random thiab txawm tias homopolymer sib tov, thiab tuaj yeem siv los ua cov thermoplastic elastomers, sib xyaw compatibilizers, thiab kev hloov kho interface thiab lwm yam.
