摘要: A novel graft polymer can include a block copolymer backbone (A) as a graft base having polymeric sidechains (B) grafted thereon. The polymeric sidechains (B) are obtainable by polymerization of at least one vinyl ester monomer (B1) and optionally N-vinylpyrrolidone as optional further monomer (B2). For example, the block copolymer backbone (A) is a triblock copolymer of polyethylene oxide (PEG) and polypropylene oxide (PPG). Also included is a process for obtaining such a graft polymer, the process is preferably carried out by free-radical polymerization.
