Carbon dioxide is a renewable, inexhaustible, and cheap alternative to fossil resources for the production of fine chemicals and plastics. It can notably be converted into exovinylene cyclic carbonates, unique synthons gaining momentum for the preparation of an impressive range of important organic molecules and functional polymers, in reactions proceeding with 100 % atom economy under mild operating conditions in most cases. This Review summarizes the recent advances in their synthesis with particular attention on describing the catalysts needed for their preparation and discussing the unique reactivity of these CO2‐based heterocycles for the construction of diverse organic building blocks and (functional) polymers. We also discuss the challenges and the future perspectives in the field.

Ultra-low density nitrile butadiene rubber (NBR)/polyvinyl chloride (PVC) composite foams that exhibit satisfactory compressive behavior and energy absorption characteristics were prepared by one-step compression molding.The properties of the NBR/PVC foams, including the density, hardness, cell morphology, compressive behavior, energy absorption characteristics, and shock absorption characteristics, were studied with various concentrations of azodicarbonamide (AC). Further that, the ideality factor and the energy absorption efficiency of the NBR/PVC foams at a low stress for application in compression and energy absorption were determined. The results revealed that

Thermoplastic elastomer Polystyrene-b-polybutadiene-b-polystyrene (SEBS) foams are prepared by using carbon dioxide (CO2) as a blowing agent via a pressure quench method. During the foaming process, various pore shapes are developed inside the foam, which is influenced by several parameters such as rigidity, solubility, and diffusivity of CO2. A previous study revealed the theory of how SEBS foams may shrink due to low rigidity and high CO2 diffusivity, but empirical verification on how the final cell properties like cell shape, cell size, cell distribution, and percentage of porosity may affect the thermal conductivity of SEBS foam is challenging to represent experimentally. This is due to difficulty in preparing foam samples at different cell shapes for the same polymer, different percentages of porosity, and cell distribution while keeping the same cell size of the SEBS foam. This paper discussed how numerical analysis is employed to investigate various properties of pores such as cell shape, cell size, cell distribution, and percentage of porosity on the thermal conductivity. The simulation results are corroborated with experimental value where the reduction of thermal conductivity is observed with a higher percentage of porosity which is shown by all cell shapes foam such as spherical, ellipse, and irregular.
