百家姓原文A block copolymer is a type of structurally organized polymer made up of two or more monomer blocks that are chemically distinct and covalently bonded together. Block copolymers molecules are formed by alternating blocks of different monomers, linked together by a single covalent bond. Block copolymers molecules can be produced via many methods, such as condensation polymerization, step polymerization, atom transfer radical polymerization (ATRP), or reversible addition-fragmentation chain transfer (RAFT).
