Backbone structure metal/metalloid polymers

In this book series, macromolecules containing metal and metal-like elements are defined as large structures where the metal and metalloid atoms are (largely) covalently bonded into the macromolecular network within or pendant to the polymer backbone. 

Polymers incorporating metals or metalloids in their backbones possess a very large variety of structural features. For example, the polymer can contain metal- or metalloid-carbon a bonds (46,47) or n bonds (48) in their backbones. " ...
