Abstract: A process for shrink-proofing wool which comprises treating the wool with specific polymers and prepolymers derived from polyoxyalkyleneamines.

Abstract: A method for imparting a softer handle to cellulosic fibres which comprises treating the fibres with a) an amino functional polymer and b) silicone polymer capable of reacting with the reactive groupings of the amino functional polymer, so as to cause the polymers a) and b) to be applied to the cellulosic fibres. The method may be performed either as a continuous process or as a batch process.

Abstract: Polymers and prepolymers derived from polyoxyalkyleneamines. The polymers and prepolymers may be used in a process for the treatment of wool so as to impart shrink resistance.

Abstract: A method for the treatment of wool so as to impart shrink resistance comprising the steps of:i) subjecting the wool to an oxidative pretreatment, andii) subsequently treating the wool with a) an amino functional polymer which itself confers a degree of shrink resistance and b) a silicone polymer capable of reacting with the reactive groupings of the amino functional polymer, so as to cause the polymers a) and b) to be applied to the wool fibers.The wool thus treated also has good rub fastness when dyed and a soft handle.

Abstract: Compounds of formula I ##STR1## can be used as optical brighteners.

Abstract: Fluid loss control additives for oil-based well-working fluids comprise a solubilized lignite derivative and an oil-swellable or oil-soluble polymer. The solubilized lignite derivative may be oil-solubilized (e.g. a lignite/amine complex) or water-solubilized (e.g. causticized lignite) and may be incorporated in a polymer matrix or added to a dispersion of a polymer in an aqueous medium.

Abstract: A fluid loss reducing additive for an oil-based well working fluid is the product of mixing together, in an oil or oil-based fluid, lignite or humic acid with an aliphatic amide or hydroxyamide, or a cyclic derivative thereof, containing no primary or secondary amine or amine salt groups.
