Development of shatter-proof greenhouse window panels from recycled PMMA

This project aims to develop a new polyrotaxane-based additive compatible with a poly(methyl methacrylate) matrix using called controlled radical polymerization technique, which is much tolerant to impurities, and thus can be carried out at a much lower cost than anionic polymerization. The new additive will provide great impact resistance to rigid poly(methyl methacrylate) at low concentrations (ideally, 1-2% by weight). As an added benefit, these additives will facilitate recycling the large amounts of PMMA protective shields currently in use in most business, for which there will be no use after the COVID-19 pandemic has ended, and for which limited recycling possibilities currently exist in Canada, even less so in terms of transforming that material into a value-added (more impact-resistant) product. This project will thus allow the diversion of huge amounts of poly(methyl methacrylate) from landfills
