Abstract
We consider a model of copolymer adsorption where the polymer is repre sented by a directed walk on the square lattice, interacting with a li ne defining a half-space to which the walk is confined. For the case o f an alternating copolymer we determine exactly the location of the ad sorption transition, and some associated critical exponents, and compa re with the values for the corresponding model for homopolymer adsorpt ion.
