Abstract

This disclosure relates to polymers and polymer compositions having monomer units of polyoxometalates and monomer units comprising hydroxy-terminated molecules such as branched molecules or dendrimers and uses in degradation, decontamination, and deodorization. In certain embodiments, the hydroxy-terminated branched molecules or dendrimers comprise terminal 1,1-tris(hydroxymethyl)methyl or 1,1,1-tris(hydroxyalkyl)methyl groups. In certain embodiments, the hydroxy-terminated molecule is N,N′,N″-tris[tris(hydroxymethyl) methyl]-1,3,5-benzenetricarboxamide.
