    Abstract: The present invention relates to novel graft polymers comprising a 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 a further monomer (B2), wherein—if present—the weight ratio of monomer (B2) to monomer (B1) is less than 0.5. The copolymer backbone (A) copolymer backbone is obtainable by polymerization of at least two monomers selected from the group of ethylene oxide, 1,2-propylene oxide, 1,2-butylene oxide, 2,3-butylene oxide, 1,2-pentene oxide or 2,3-pentene oxide, the distribution of the alkylene oxide moieties within the copolymer backbone being in random order, and the molecular weight of the copolymer backbone Mn in g/mol being within 500 to 7000. Further claimed is a process for obtaining such a graft polymer, preferably being carried out by free-radical polymerization. Also claimed is the use of such a graft polymer within, for example, fabric and home care products, and fabric and home care products containing such a graft polymer.
