Abstract
The invention relates to a composition comprising a plastic and an additive, the additive being present in a dendrimer having functional end groups, said functional end groups being provided, at least in part, with a modifying group, which modifying group is compatible with the plastic. The additive remains trapped in the dendrimer and, owing to the presence of the modifying group on the dendrimer, cannot migrate or bleed from the plastic.
