ChemSusChem

Huang K, Liu F, Jiang L, Dai S.
PMID: 28865092
ChemSusChem. 2017 Nov 09;10(21):4144-4149. doi: 10.1002/cssc.201701666. Epub 2017 Oct 13.

Meso-macroporous polymers possessing nitrogen functionality were innovatively synthesized through an aqueous and template-free route herein. Specifically, the polymerization of 1-(4-vinylbenzyl)-1,3,5,7-tetraazaadamantan-1-ium chloride in aqueous solution under high temperatures induces the decomposition of the hexamethylenetetramine unit into ammonia and formaldehyde molecules,...
