MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202517066559 A) filed by Basf Se, Ludwigshafen am Rhein, Germany, on July 11, for 'biodegradable graft polymers as dye transfer inhibitors.'
Inventor(s) include Mueller, Jan Ole; Benlahmar, Ouidad; Ebert, Sophia; Schoen, Florian; Molawi, Kian; Blanazs, Adam; and De, Swati.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "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 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. 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 compositions and products, such as fabric and home care products, containing such graft polymer. The graft polymers are specifically employed in cleaning compositions as dye transfer inhibitor."
The patent application was internationally filed on Dec. 08, 2023, under International application No.PCT/EP2023/084830.
