Abstract
Synthetic resins having a topologically interpenetrating polymeric network comprise macrocyclic structures of chemically different, crosslinking polymers which are permanently entangled with each other. The several macrocyclic structures that are present are characterized by the absence of chemical bonds between the individual networks.
