Complexities Uniquely Linked to Network Rigidity

Flexible networks are most commonly prepared by one of two methods polymerizing an appropriate mixture of monomers in one step, as in the case of styrene-divinylbenzene or polyurethane networks, or by first preparing long 

All these matters have arisen in the appropriate positions in the previous Sections. We now describe them as problems in greater detail in the hope that they may stimulate further interest.
