Micromechanisms of crystalline polymers |
| |
- The yield stress of semicrystalline polymers depends not only on crystal thickness but also on the degree of crystallinity.
- An earlier proposed mechanism for yielding connected with non-crystallographic changes of the material is discussed
- It will be shown that plastic yielding of semicrystalline polymers is greatly affected by the state of their amorphous phase
- The changes of the amorphous phase may explain why yielding is depending on the crystallinity degree
