| 摘要 |
The invention concerns compositions based on semicrystalline thermoplastic resins and ABC block copolymers resulting in materials or objects having improved impact strength, elongation at break, resistance to stress cracking and deformation, thermal resistance relative to semicrystalline resin(s) on their own or mixed with conventional shock-resistant additives while maintaining a high modulus, therefore a certain rigidity. They are generally suitable for producing objects such as sheets, films, tube sheathing, pipes, tubes, yarns, strands, cable sheaths, guy lines, impervious sheaths, sleeves, monolayers or multilayers, components, moulded plates, thermoformed parts, sections, bottles, powders for coating substrates. The materials or object resulting from said compositions have characteristic morphology visible in electronic microscopy.
