Highly elastic and degradable thermoset elastomers from CO2-based polycarbonates and bioderived polyesters†
Abstract
The first example of CO2-based thermoset elastomers (CO2Es) on the basis of two sustainable and degradable polymers, rigid CO2-based polycarbonates and soft polyesters, is reported. The elastomers exhibit acceptable mechanical strength and excellent elasticity (average elastic recovery >93%) by introducing a chemical network. By adjusting the ratio of rigid CO2 polycarbonate/soft polyester, green elastomers with adjustable mechanical performance are obtained efficiently.
