Modified L-lysine polymers are provided consisting essentially of recurring units of the formula: [-CO-CH-NH-] ¦ (CH2)4 (I) ¦ R and recurring units of the formula: [-CO-CH-NH-] ¦ (CH2)4 (II) ¦ NH2 the total number of recurring units of formula (I) being n and the total number of recurring units of formula (II) being m such that n + m is greater than 50 with the proviso that m can be zero, in which each R radical which may be the same or different, represents one of the following groups: -NH-SO3H: -NH-(CH2)p-SO3H in which p is 1 to 4 ; -NH-(CH2)2-COOH; -NH-CO-CH2-CH2OH; -NH-CO-(CH2)2-SO3H; -NH-CO-NH2; -NH-C-NH2; PARALLEL NH -OH and - N(CH3)2. |
