• Recent Improvements: Advances in polymerization processes have improved the thermal stability of CO₂-based polymers. For example, the use of polymeric additives or composite materials has been shown to significantly increase the heat resistance of CO₂-derived polymers, enabling their use in higher-temperature environments Additionally, the development of block copolymers that combine CO₂-derived segments with other high-performance materials has shown promise in extending the temperature range in which these polymers can be used.
