Test of the Assumption of the Scaling Law for Polymer Monolayers

Abstract
The assumption of the scaling law, that the monomer structure remains constant as the polymer concentration changes from the dilute to semidilute regime, has been tested by use of optical second-harmonic generation. The monomer orientation does not change as the polymer concentration is increased. This observation is the first confirmation of the basic assumption of the scaling law which describes polymer behavior in two-dimensional space.
