Abstract:
The use of an alkoxylated polytetrahydrofurane of formula wherein m, m′, n, n′, p, p′ and k are integers in the range of ≧1, R1 denotes an unsubstituted linear or branched alkyl radical, R2 denotes —CH2—CH3, and R3 denotes a hydrogen atom or —CH3, as an additive in a fuel for reducing fuel consumption in the operation of an internal combustion engine with this fuel.
Abstract:
This application relates to biodegradable graft polymers for use as 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 vinyl ester, at least one vinylimidazole-monomer or derivative thereof in amounts of more than 10 weight percent being based on the total weight of the graft polymer, and optionally at least one vinyl lactame in the presence of the polymer backbone. The inventive graft polymers exhibit dye transfer inhibition properties; as they also are bio-degradable, they are useful polymers for laundry cleaning applications to prevent dye transfer. The invention further relates to the production of such graft polymers. Furthermore, the present invention relates to the use of such a graft polymer within fabric and home care products, and the use of such graft polymers for inhibiting the dye transfer in laundry applications. This invention also relates to fabric and home care products as such containing such a graft polymer.
