In this paper we calculate the mean-square end-to-end distance and the mean-square perpendicular distance of chemically adsorbed copolymers of type A-B. The adsorbed monomers are assumed to be a quenched system. The calculation of the mean-square end-to-end distance shows that this distance is fully determined by the frozen-in disorder of the adsorbed monomers. The result obtained for mean-square perpendicular distance predicts a dependence of the fraction of adsorbed monomers. In comparison with homopolymers there is a difference within the power law behaviour, but no difference occurs for the physical adsorption of copolymers.
