Branching (polymer chemistry) - Wikipedia
网页In polymer chemistry, branching is the regular or irregular attachment of side chains to a polymer 's backbone chain. It occurs by the replacement of a substituent (e.g. a hydrogen atom) on a monomer subunit by another covalently-bonded chain of that polymer; or, in the case of a graft copolymer, by a chain of another type.
