Aminoglycoside-polyamines are disclosed along with methods of use thereof in displacement chromatography and as DNA-binding ligands. The aminoglycoside-polyamines are derivatives of carbohydrates, such as sugars, amino sugars, deoxysugars, glycosides, nucleosides and their substituted counterparts. The subject polyamines possess a
group in place of at least one hydrogen atom of at least one hydroxyl group of the carbohydrate compound. In these compounds R
1
is an alkyl group or an azaalkyl group, and R
2
is a primary or secondary amino group.
Die Erfindung betrifft amorphe, weiche Polyamide mit Elastomercharakter und mit einer Glastemperatur von weniger als + 10° C auf Basis von Dimerfettsäuren und speziellen disekundären Diaminen, die Herstellung wie auch die Verwendung dieser elastomeren Polyamide als Kautschuk, Weichmacher bzw. insbesondere Schlagzähmodifikatoren für Thermoplaste oder als Weichsegmente zum Aufbau thermoplastischer Elastomerer und Additive für andere Zwecke.

Provided are: an antistatic agent which is capable of imparting excellent antistatic effect in a small amount and has sufficient persistence and wiping resistance; an antistatic agent composition; an antistatic resin composition; and a molded article. The antistatic agent comprises a polymer compound (E) having a structure in which a block polymer (C) and an epoxy compound (D) are bound via an ester bond formed by a carboxyl group of the block polymer (C) and an epoxy group of the epoxy compound (D), the block polymer (C) having a structure comprising carboxyl groups at both ends, in which structure a block constituted by a polyester (A) having carboxyl groups at both ends and a block constituted by a compound (B) having hydroxyl groups at both ends are repeatedly and alternately bound via ester bonds formed by the carboxyl groups and the hydroxyl groups, and the epoxy compound (D) comprising two or more epoxy groups.
