The Group IVA elements represent the most dramatic transition from non-metallic (carbon), to metal-like (silicon to germanium) to metallic (tin and lead) of any family. This collection of 11 reviews cover germanium, tin, and lead polymers as well as polymers containing group IVA metals and metal-like elements. Specific topics include an overview of group IVA polymers, hyperbranched poly(silylenearylene)s, silole-containing conjugated polymers, silica polyamine composites, polyhedral oligomeric silsesquioxane polymers, copolymers, resin nanocomposites, polymer hybrids containing silca- and silsesquioxane, siloxane elastomers and copolymers, bioinspired silica synthesis, organogermanium polymers, organotin polymers, and organolead-containing polymers. The editors provide a general index.
