SAXS investigations have shown [10] that the introduction and gradual increase of the S-co-AA content in the CPU matrix results in the increase of the packing degree of the flexible blocks in the CPU crystallites and in a gradual 

The mechanical properties of the thermoplastic AIPNs, such as density, p, flow limit, (Tf, elasticity modulus, E, and tensile strength, a, change non-additively with composition, showing extreme values at low contents (5 to 10 wt%) of CPU or S-co-AA (Table 2). This behavior confirms that each component in the thermoplastic AIPNs affects the microphase structure and properties
