Flexible polymer networks: rubber elasticity and segmental orientation

Abstract Thermoreversible networks are very attractive materials because of a large variety of suitable thermoreversible chemical bonds which can be used for crosslinking. In future, to certain extent, they may replace so far used irreversibly crosslinked networks and contribute to more sustainable material concepts also in the field of crosslinked elastomers. This paper gives some theoretical basis for understanding the elastic deformation properties of crosslinked polymers and presents some experimental tools for studying deformation behavior not only on a macroscopic length scale but also on a segmental scale. Basic knowledge of these two topics is useful for chemists and material scientists when designing new sustainable elastomeric polymer networks.
