Abstract

The invention pertains to an oligomer or polymer substituted by one or more bisacylphosphine oxide moieties, characterized in that said bisacylphosphine oxide moiety is linked via the phosphorous atom, optionally via a spacer group, to the oligomer or polymer backbone; as well as to specifically functionalized bisacylphosphine oxides, suitable to prepare said polymers or oligomers.
