WebPerformance Series Smart Series In polymer chemistry, graft polymers are segmented copolymers with a linear backbone of one composite and randomly distributed branches of another composite. The picture labeled "graft polymer" shows how grafted chains of species B are covalently bonded to polymer species A. Although the side chains are structurally distinct from the main chain, the individual grafted chains may be homopolymers or copolymers. Graft polymers have been synthesized for many decades … WebStyrenic Block Copolymers (TPE-S) โดยที่นิยมในตลาดคือ SBS (Styrene Butadiene Block Copolymer) และ SEBS (Styrene Ethylene Butadiene Block Copolymer) TPE-S … bw 揺れる草むら 条件
