Free Radical Copolymerization of 1,3-Cyclooctadiene with Maleic Anhydride or N-Substituted Maleimides: A Simple Way to High-Performance Transparent Plastic Herein, we reported the free radical copolymerization of 1,3-cyclooctadiene and maleic anhydride or N-Substituted Maleimides. The obtained alternating copolymers with fine-tuned Tg (ranging from 62 ℃ to 300 ℃) and excellent properties on thermal resistance and optical properties (up to 90% transmissivity).

AbstractPolyvinyl chloride (PVC) is the world’s third-most widely manufactured thermoplastic, but has the lowest recycling rate. The development of PVC-like plastics that can be depolymerized back to monomer contributes to a circular plastic economy, but has not been accessed. Here, we develop a series of chemically recyclable plastics from the reversible copolymerization of cyclic anhydride with chloral.

1. IntroductionIn the field of remote sensing, hyperspectral imaging (HSI) technology plays a crucial role in various domains such as environmental monitoring, resource management, and agriculture [1,2,3]. This technology provides rich spectral information by capturing images across numerous contiguous spectral bands, enabling a detailed analysis and identification of materials based on their spectral signatures.

AbstractOur society is pursuing chemically recyclable polymers to accelerate the green revolution in plastics. Here, we develop a recyclable polyester library from the alternating copolymerization of aldehyde and cyclic anhydride. Although these two monomer sets have little or no thermodynamic driving force for homopolymerization, their copolymerization demonstrates the unexpected alternating characteristics.

The development of metal-free catalysts with excellent activity and controllability remains a significant obstacle for the copolymerization of CO2 and epoxides. In this study, we used the frustrated Lewis pair (FLP) composed of commercial tertiary phosphine and trialkylborane to catalyze the copolymerization of CO2 and propylene oxide (PO).
