Changes in the chain architecture of polymers influence the whole behavior of polymers, like the glass transition temperature or dynamics. Due to the entropic effects of the chain conformation and the enthalpic effects of the added endgroups the adsorption and the phase behavior differ from the one of linear polymer chains. Regular starlike polymers are a special class of branched polymers which show a spread behavior depending on their functionality (number of arms) and the molecular weight of the arms. Thus they are a link for the understanding of the behavior of linear polymers up to micelles. We investigate the adsorption and the phase behavior of regular starlike polymers with different number of arms and arm weight.
