(EN) Hyperbranched aramids, made from an aromatic aminodicarboxylic acid or an aromatic diaminocarboxylic acid, and optionally an aromatic aminocarboxylic acid are disclosed. The hyperbranched aramids are useful as aids for the processing of aramid solutions. Also disclosed are novel monomers used to make the hyperbranched aramids.(FR) Cette invention concerne des aramides hyperramifiées produites à partir d'acide aminodicarboxylique aromatique ou d'acide diaminocarboxylique aromatique. Les aramides hyperramifiées sont utiles dans le traitement des solutions d'aramides. De nouveaux monomères utilisés pour produire les aramides hyperramifiées sont également présentés.

A series of novel cyclic peptides possessing an alternate natural / non-natural amino acid sequence were prepared from L-alanine and 5-(N-acylamino)-3-aminobenzoic acid with a long acyl chain. Upon examination by the voltage clamp method, membranes composed of the synthetic cyclic peptides with varying ring sizes and side-chain lengths were found to form cation selective channels with a conductance
