Abstract
Disclosed herein are novel graft polymers including a block copolymer backbone (A) as a graft base having polymeric sidechains (B) grafted thereon. The polymeric sidechains (B) are obtainable by polymerization of a 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). Further disclosed herein is a process for obtaining such a graft polymer. Further disclosed herein is a method of using such a graft polymer within, for example, fabric and home care products. Additionally disclosed herein are fabric and home care products containing such a graft polymer.
