Polymer composition containing a semi-crystalline or glass-forming polymer in a rigid phase and, as impact modifier therein, a rubbery polymer in a dispersed phase |
摘要 |
The invention relates to a polymer composition containing a semi-crystalline or glass-forming polymer in a rigid phase and, as impact modifier therein, a rubbery polymer. The polymer composition according to the invention is characterized in that it has no morphological inhomogeneities with a diameter larger than 40, preferably 20 micrometer as visible on a Scanning Electron Microscopy (SEM) picture of the surface of fracture of a test bar broken in a fatigue test. As a result, the elongation at break, the fatigue resistance and the total useful service life of an object manufactured from this composition are much higher.
