  Experimental observations and computer simulations have recently revealed
universal aspects of polymer solution behaviour that were previously unknown.
This progress has been made possible due to developments in experimental
methodologies and simulation techniques, and the formulation of scaling
arguments that have identified the proper scaling variables with which to
achieve data collapse, both for equilibrium and nonequilibrium properties. In
this review, these advances in our understanding of universal polymer solution
behaviour are discussed, along with a brief overview of prior experimental
observations and theoretical predictions in order to provide a context for the
discussion. Properties for which the existence of universality is still
unclear, and those for which it has not yet been verified theoretically are
highlighted, and theoretical predictions of universal behaviour that require
experimental validation are pointed out.
