Abstract: The present invention relates to novel graft polymers comprising a polymer 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 a further monomer (B2), wherein - if present - the weight ratio of monomer (B2) to monomer (B1) is less than 0.5. The polymer backbone (A) is obtainable by polymerization of ethylene oxide, and the molecular weight of the polymer backbone Mn in g/mol is within 500 to 5000. The present invention further relates to a process for obtaining such a graft polymer, the process is preferably carried out by free-radical polymerization. The present invention also relates to the use of such a graft polymer within, for example, fabric and home care products. Also claimed are fabric and home care products containing such graft polymer.

Abstract: The present invention relates to novel graft polymers comprising 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). Most preferably, the block copolymer backbone (A) is a triblock copolymer of polyethylene oxide (PEG) and polypropylene oxide (PPG). The present invention further relates to a process for obtaining such a graft polymer, the process is preferably carried out by free-radical polymerization. Furthermore, the present invention relates to the use of such a graft polymer within, for example, fabric and home care products. Another subject-matter of the present invention are fabric and home care products as such, containing such a graft polymer.
