Abstract (en)
[origin: DE19848873A1] A composition containing: (X) a biologically degradable polymer and (Y) at least one fluorescent dye is new. Independent claims are also included for: (1) An acid component (A) from: (a1) 30-95 mole% of at least one aliphatic or cycloaliphatic dicarboxylic acid, an ester forming derivative, or a mixture of these, (a2) 5-70 mole% of at least one aromatic dicarboxylic acid or an ester forming derivative, or a mixture of these, (a3) 0-5 mole% of a compound containing sulfonate groups; (B) a diol component selected from: at least one 2-12C alkanediol and at least one 5-10C cycloalkanediol or their mixtures, and optionally one or more components selected from: (C) a component selected from: (c1) at least one ether-functional dihydroxy compound of formula (I): HO((CH2)n-O)m-H (I) HO-(C(O)-G-O-)pH (IIa) n = 2,3, or 4, and m = 2-250, (c2) at least one hydroxycarboxylic acid of formula (IIa) or (IIb): p =1-1500, r = 1-4, G = a residue selected from phenylene, -(CH2)q-, where q = 1-5, -C(R)H-, and -C(R)HCH2, where R = Me or Et, (c3) = at least one 2-12C amino-alkanol or at least one 5-10C-aminocycloalkanol or their mixtures, (c4) = at least one 1-8C diaminoalkane, (c5) = at least one 2,2-bisoxazoline of formula (III): where R<1> = a single compound, a (CH2), with z-alkylene groups, with z = 2,3, or 4, or phenyl, (c6) = at least one aminocarboxylic acid, selected from a group consisting of natural aminoacids, polyamides of maximum molecular weight 18000 g/mol, obtainable by polycondensation of a 4-6C dicarboxylic acid and a 4-10C diamine, compounds of formula IVa and IVb: where s = 1-1500, and t = 1-4, and T = a residue selected from a group consisting of phenylene, -CH2)n-, where n = 1-12, -C(R<2>)H-, and -C(R<2>)HCH2, where R<2> = Me, Et, polyoxazoline with the recurring unit V: where R<3> = H, 1-6C alkyl, 5-8C cycloalkyl, unsubstituted or substituted with 1-4C alkyl up to 3-fold substituted phenyl, or equals tetrahydrofuryl, or mixture of (c1) to (c6); and (D), a component selected from: (d1) at least one compound with at least 3 groups able to form esters , (d2) at least one isocyanate, and (d3) at least one divinylether, or a mixture of (d1) to (d3); (2) a shaped body, film, or fibers obtained from the composition; (3) a process for labelling a biologically degradable polymer (X) involving mixing it with at least one fluorescent dye (Y) in an amount such that a fluorescence is produced which can be detected by a detector when the composition is subjected to electromagnetic radiation; (4) sorting of a compost mill, where the biologically degradable polymer contained in it is detected, loaded into the compost mill, and the unlabelled biologically undegradable polymer is removed from the compost mill.
