ABSTRACT:
Embodiments relate to viscosifiers that are terminated polymers that have functional terminal groups. The polymers being pre-extended by polyepoxides and being reacted to give polymers that are terminated by other functional groups. The viscosifiers have a low content in educts or educt descendants that deteriorate the properties of compositions and considerably reduce or even exclude the formation of high-molecular addition products so that the products obtained have low viscosity and good storage stability.
