General description
Polybutadiene, cis (PB-cis) is a synthetic rubber that is prepared by solution polymerization of 1,4-butadiene. Its mechanical properties include low temperature flexibility and abrasion resistance. It can be cured by using sulfur based donors and peroxides and thus PB-cis acts as a highly cross-linked polymer with high resilience.
Application
PB-cis can be polymerized with styrene for the formation of high impact polystyrene (HIPS). It may also be used as a toughening agent for acrylonitrile butadiene rubber (ABS) based resins.

In recent years, there is aroused interest in expressing complex systems as networks of interacting nodes. Using descriptors from graph theory, it has been possible to classify many diverse systems derived from social and physical sciences alike. In particular, folded
