Abstract
An expression for the determination of the cross-over point concentration, CX, of the polymer in a number of solvents has been derived, and an expression relating Cx with the unperturbed dimension of polymer molecules (r0 2)½ has been proposed. The unperturbed dimensions for polymethyl acrylate, polyethyl acrylate, polybutyl acrylate, polyacrylonitrile, and polyvinyl pyrrolidone have been calculated.Keywords
