In effort to address challenges in the efficient synthesis of highly functional block copolypeptides, we report use of a combination of functional monomer polymerization and postpolymerization modification to obtain new double hydrophilic block copolypeptides with desirable properties. We prepared copolymers that contain discrete hydrophilic, nonionic poly(l‐methionine sulfoxide) and Ca2+ ion binding poly(l‐phosphonohomoalanine) segments. The facile and selective postpolymerization conversion of inexpensive, readily prepared poly(l‐methionine) segments into nonionic, hydrophilic poly(l‐methionine sulfoxide) segments reduces the need for use of combinations of protecting groups. The complex copolypeptides prepared using this strategy were able to promote formation of CaCO3 microspheres with tunable polymorphism. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

“…Sr was readily included in the perovskite lattice structure as Ca site was substituted, which resulted in high immobilization capacity and promoted chemical stability. Borovinskaya et al . have employed the SHS technique to synthesize perovskite, zirconolite, rutile, pollucite, and Y 2 Ti 2 O 7 pyrochlore mineral phases for HLW immobilization, where Fe 2 O 3 and Ca(NO 3 ) 2 were employed as the oxidants.…”

Synroc is recognized as the second generation waste form for the disposal of high-level radioactive waste (HLW). In this research, one of the mostly studied Synroc minerals, zirconolite (CaZrTi 2 O 7 ), was prepared by self-propagating high-temperature synthesis (SHS). CuO and MoO 3 were employed as the oxidants with Ti as the reductant. Different TiO 2 /Ti ratios were selected to investigate reactivity and adiabatic temperature (T ad ) of the designed SHS reactions. Zirconolite was successfully synthesized as the main phase at varied TiO 2 /Ti ratios using CuO and MoO 3 as the oxidants. The as-synthesized samples were readily solidified with desirable density and Vickers hardness.
