  Experimental results from mechanical viscoelastic as well as dielectric
relaxation times were compared to theoretical expectations utilizing polymer
scaling theory. Viscoelastic relaxation of a hydrogel at 33% relative humidity
fabricated from co-poly-L-(glutamic acid$_{4}$, tyrosine$_{1}$) [PLEY(4:1)]
crosslinked with poly-L-lysine scaled with concentration according to reptation
dynamics. High frequency dielectric relaxation of aqueous copolymer PLEY(4:1)
scaled with concentration as an ideal chain and aqueous Poly-L-glutamic acid
scaled as an extended chain. The study shows that two seemingly different
measurement methods can yield information about the state of polymer chain
conformation in situ.
