Chain Transfer to Polymer: A Convenient Route to Macromonomers
WebSponsored by Wyatt Technology Feb 7 2014. Branching is a key structural parameter of many natural and synthetic polymers and has a considerable impact on a variety of … 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 … See more A graft polymer molecule is a branched polymer molecule in which one or more of the side chains are different, structurally or configurationally, from the main chain. A star-shaped polymer molecule is a branched polymer … See more The branching index measures the effect of long-chain branches on the size of a macromolecule in solution. It is defined as g = /, where sb is the mean square radius of gyration of the branched macromolecule in a given solvent, and sl is the mean square … See more In free radical polymerization, branching occurs when a chain curls back and bonds to an earlier part of the chain. When this curl breaks, it leaves small chains sprouting from the … See more • Media related to Branching (polymer chemistry) at Wikimedia Commons See more la mesita family shelter
