    Abstract: Use of copolymers obtainable by free-radical copolymerisation of (a) C8-C40-monoolefins with (b) ethylenically unsaturated C4-C8-dicarboxylic anhydrides in the manner of a mass polymerisation at from 80 to 300 DEG C to form copolymers having molecular weights of from 500 to 20,000 g/mol, subsequent solvolysis of the anhydride groups of the copolymers and at least partial neutralisation in an aqueous medium with bases of the carboxyl groups formed in the course of the solvolysis and which are present in the form of aqueous dispersions or solutions, as agents for waterproofing leathers and pelt furs.

    Abstract: Aminomethylene phosphinic acid derivs. contg. units of formula (I), soluble in hydrocarbons, or aminomethylene phosphonic acid derivs. contg. units of formula (Ia), or aminomethylene phosphonic acid derivs. of formula R R N-(A-N(R ))pR (II), are used in the extn. of Fe ions from aq. solns. In the formulae: R and R = H, 1-30 C alkyl (opt. carrying up to 15 OH gps. and/or broken by up to 14 non-adjacent O atoms), or 2-30 C alkenyl, 7-18C aralkyl, or 6-14C aryl (opt. substd. with up to 3 1-12C alkyl or alkoxy, halogen, CN, OH or 1-4C alkoxycarbonyl; R -R = H, 1-30 C alkyl (opt. carrying up to 15 OH gps. and/or broken by up to 14 non-adjacent O atoms), 2-30 C alkenyl, 7-18C aralkyl, 6-14C aryl (opt. substd. with up to 3 1-12C alkyl or alkoxy, halogen, CN, OH or 1-4C alkoxycarbonyl), or are gps. of formulae -CR R -PO3H2, -CH2-COOH or -CH2-CH(OH)-R ; at least one of the gps. R -R = -CR R -PO3H2, and at least one other is 6-30C alk(en)yl, 7-18C aralkyl, (substd.) 6-14C aryl or -CH2-CH(OH)-R ; R = 6-30 C alk(en)yl, 7-18C aralkyl or (substd.) 6-14 C aryl; A = 1-12C alkylene (opt. substd. with up to 3 1-30 C alkyl, 2-30C alkenyl, 7-18C aralkyl, or 6-14C aryl, which in their turn may be substd. by up to 3 1-12C alkyl or alkoxy, halogen, CN, OH, or 1-4C alkoxycarbonyl); and p = 0-30,000. Also claimed is a modifier for use in the sepn. of metal ions from aq. solns. by solvent extn..
