Metal-containing polymer groups

Overall, ADMET polymerization is an advantageous strategy for synthesizing transition metal-containing polymers because of the functional group tolerance of the metathesis catalysts employed, the mild conditions under which it operates, the wide range of accessible architectures, and the precise structural control afforded by the method. 

For many applications, side-chain metal-containing polymers are sufficient. However, to access the most profound alterations in polymer properties that arise from the presence of metal atoms in a polymer structure, incorporation in the main chain is required. Potential advantages of including metals in the backbone of a polymer rather than the side-group structure include the following ...

Depending on the metal nature and monomer structure, the vapor deposition cryopolymerization of metal-monomer systems yields a possibility producing metal-containing polymers of different structure. Polymer containing organo-metallic groups or metal-polymer complexes can be prepared using pre-... 

A very promising variant on this type of condensation polymerization involves the use of monomers that possess groups X and Y, which can be eliminated from the same molecule. This circumvents the need for careful control of reaction stoichiometry. Moreover, in certain cases, polymerization of monomers of this type can follow a chain-growth type of mechanism that leads to high molecular weights much more easily. Such processes (Scheme 1.1, Route C) have not yet been explored for the formation of metal-containing polymers, but are well-established for the synthesis of certain classes of polymers based on main-group elements such as polyphosphazenes (1.2) and polyoxothiazenes (1.4) [12, 16, 26].

Polymers containing Hf(TV) in the main chain or side chains can be prepared by any of the known processes for synthesis of metal-containing polymers. An attractive approach is the polycondensation of dicyclo-pentadienyl derivatives of hafnium(IV) with diols or oxygen-free diacetylenic hgands. An alternative approach is polymerization of the Hf(TV) monomers with (meth)acrylate and fumarate groups, synthesized for the first time in this study. We investigated the thermolysis of the synthesized...
