Abstract
De Genne's theory (1971) on the Brownian motion of a polymer chain in the presence of fixed obstacles is generalized so as to take into account the concentration of obstacles. The molecular weight dependences of the characteristic relaxation time and the self-diffusion constant of the chain are found to change continuously from de Gennes-type to Rouse's as the concentration of obstacles decreases.Keywords
