  • Publication number: 20260201279
    Abstract: Graft polymers, their preparation and use such as in cleaning compositions, wherein the graft polymers comprise as polymer backbone (A) a polyalkylene oxide ester polymer with a weight average molecular weight Mw of 500 to 50 000 g/mol, comprising 10 to 560 ether groups and 2 to 51 ester groups, which are interconnected with alkylene groups, which is significantly better biodegradable than conventional polyalkylene oxide polymers, and polymeric side chains grafted onto the polymer backbone A, wherein said polymeric sidechains (B) are obtainable by co-polymerization of at least one monomer selected from (B1), and (B2), with the monomers (B1) being at least one vinyl ester monomer, (B2) with (B2a) and optionally (B2b), with (B2a) at least one olefinically unsaturated amine-containing monomer, preferably being 1-vinylimidazole or its derivatives, and optional (B2b) at least one further nitrogen-containing monomer, being preferably a vinyllactame-monomer.

  • Publication number: 20250326993
    Abstract: Novel graft polymers having a polymer backbone (A) as a graft base having polymeric sidechains (B) grafted thereon. The polymeric sidechains (B) are obtainable by polymerization of optionally (B1) at least one vinyl ester monomer, at least one, preferably a least two nitrogen-containing monomer (B2), and optionally further monomer(s) (B3). The polymer backbone (A) comprises polyalkylene-oxide-derived moieties and moieties derived from lactone(s) and/or hydroxy acid(s), those moieties being mixed such that the polymer backbone contains ester-functions within the polymer chains. Process for obtaining such a graft polymer, the process is preferably carried out by free-radical polymerization. Use of such a graft polymer within, for example, fabric and home care products. Compositions and products, such as fabric and home care products, containing such graft polymer. The graft polymers are preferably employed in cleaning compositions as dye transfer inhibitor.

  • Publication number: 20250297192
    Abstract: This application relates to biodegradable graft polymers for use as e.g. dye transfer inhibitors especially in laundry applications. The graft polymers of the invention comprise a polyalkylene oxide polymer as polymer backbone of the graft polymer and grafted side chains obtained from radically polymerizing at least one vinylimidazole-monomer or derivative thereof, and at least one vinyl lactame and optionally further monomers in the presence of the polymer backbone. The inventive graft polymers exhibit among others dye transfer inhibition properties: as they also are bio-degradable. they are especially useful polymers for fabric and home care and cleaning applications to prevent dye transfer. The invention further relates to the production of such graft polymers.
