    摘要: This invention relates to amorphous, flexible elastomeric polyamides based on dimer fatty acids and special disecondary diamines which have a glass transition temperature below 10.degree. C., to the production of these elastomeric polyamides and to their use as rubbers, plasticizers and, in particular, high-impact modifiers for thermoplastics or as flexible segments for the synthesis of thermoplastic elastomers and as additives for other purposes.
