Abstract
The paper concerns the polymers built of oligoamide hard blocks and oligoamide soft blocks (KPAA, formula I). Oligo(laurolactam) (PA12) was used as hard block and the product of reaction of dimerized fatty acid and hexamethylene diamine (PA6,36) was used as a soft one. Effects of molar ratio of these blocks on the following properties of KPAA have been investigated: limiting viscosity number ([2]), degrees of swelling in water and benzene (***, Qbenz, respectively), tensile properties and values of phase transition temperatures (Table 1, Fig. 1). It was found that fulfilling of various requirements concerning functional properties was possible when KPAA composition was properly chosen.
