Experimental tests of the scaling law predictions

Comparison of experimental exponents in the semi-dilute regime with the theoretical predictions 

The consonance noted above between the predictions of scaling law theories and the results of experiments suggests that the assumptions underlying the theories are correct. Mattice (1981), however, has criticized the basic assumptions of the blob concept because they are not verified by rotational isomeric state calculations that incorporate the excluded volume term, admittedly in a somewhat empirical fashion. A major difficulty envisaged by Mattice in the simple application of the blob concept lies in its failure to account for the consequences of the repulsive interaction of the subchain with atoms elsewhere in the main chain.
