Amorphous polymers entanglement molar mass

The entanglement molar mass Me for PE is 1.7 kg.mof. The ratio M c/Mg ranges thus between 23 and 59 versus 5 for low crystalline or amorphous polymers. This means that embrittlement occurs while the... [Pg.165]

Within this framework, one can imagine a two dimensional ductile-brittle transition criterion which would be composed of two perpendicular boundaries in the graph la-Mw (Fig. 7). The vertical boundary would correspond to a critical molar mass M c- In polymers of low crystallinity or fully amorphous, M c would be sharply linked to the entanglement molar mass M c 5Me. In polymers of medium to high crystallinity, M c would be the molar mass below which it is impossible to have values higher than lac- The horizontal boundary would correspond to U = lac-... [Pg.169]
