Polyvinyl chloride is one of the world\u2019s most widely produced plastics, yet recycling remains a major challenge due to its high chlorine content and limited compatibility with standard processes. A team from the University of Mons has now explored the use of CO\u2082-binding alcohols (CO\u2082BALs) to chemically modify PVC, paving the way for improved upcycling.<\/strong><\/p>\n\n\n

The research focused on 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD)-based CO\u2082BALs as nucleophiles for PVC functionalisation. The influence of solvent polarity, conversion rates and reaction times on the substitution-to-elimination ratio was systematically investigated.<\/p>\n\n\n\n

High selectivity and thermal stability<\/h3>\n\n\n\n

Although the substitution degree remained below 10 wt\u202f%, an impressive SN2\/E2 selectivity of 94\/6 was achieved. Using \u00b9H-NMR, FT-IR, SEC and TGA, the team confirmed successful grafting of carbonate groups and observed trends in thermal stability. However, CO\u2082BAL stabilisation in polar solvents may limit reactivity.<\/p>\n\n\n\n

To overcome this challenge, alternative approaches such as flow chemistry are being considered to improve substitution efficiency. Overall, this work demonstrates the potential of CO\u2082-based strategies to bridge the gap between polymer upcycling and green chemistry.<\/p>\n\n\n\n
