09002 IUPAC Gold Book - chain-walking polymerization 10.1351/goldbook.09002 09002 current initialism: CWP 1 Coordination polymerization in which the chain carrier migrates along the formed polymer chain through a series of \(\ce{\upbeta\mbox{-}hydrogen}\) eliminations and reinsertions with inversion of stereochemistry. In contrast to classical coordination polymerizations, which provide linear polyethylene, CWP of ethylene leads to a branched polymer. CWP of \(\ce{\upbeta\mbox{-}olefins}\) generally leads to less branched polymers than those formed by classical coordination polymerization.
