Thiol-ene Click Chemistry Incorporates Hydroxyl Functionality on Polycyclooctene to Tune Properties.

Polyolefins compose the majority of plastic waste, but conventional mechanical recycling degrades their properties, thereby reducing their value. We report the functionalization of a model for dehydrogenated polyethylene, polycyclooctene (PCOE), with thiol-ene click chemistry to install pendant hydroxyl ethyl thioethers. Functionalization of PCOE using mercaptoethanol via thiol-ene click chemistry yielded functionalization between 1.

Single-Step Synthesis of Atmospheric CO Sorbents through Radiation-Induced Graft Polymerization on Commercial-Grade Fabrics.

Primary amines form a key component of a well-studied mechanism for capturing carbon dioxide (CO) from the atmosphere. This study comprises a single-step synthesis of a novel sorbent for CO by grafting monomers rich in primary amines to three commercial-grade fabrics: polyethylene terephthalate, high-density polyethylene and nylon 6. An initial evaluation of the sorbency of the chosen monomers, allylamine and butenylamine, qualitatively confirmed their ability to extract CO from the atmosphere.
