    • Apart from cross-linking other factors influence the "rigidity" of a polymer, and a general correlation between the rigidity or microviscosity of a network and the degree of cross-linking can not be made. For example, if 1 is dissolved in MMA a 115 nm shift (from 680 to 565 nm) is observed upon polymerization, despite the fact that PMMA is a linear polymer.
