Abstract
A branched, hybrid polymer obtainable by an addition polymerisation process, preferably a free-radical polymerisation process, comprising organic chains and inorganic chains wherein: (a) said polymer comprises at least two organic chains which are covalently linked by a bridge other than at their ends, (b) at least one inorganic chain is present, either as a covalently-bonded pendant group on an organic chain or within the bridge, and (c) the polymer comprises a residue of optionally but preferably a chain transfer agent and a residue of an initiator, optionally but preferably a free-radical initiator. The invention further provides a method for the synthesis of these polymers.
