Abstract: | Summary: Cavitation in low molecular weight liquids under tension and in crystalline polymers during tensile drawing was recapitulated. The review indicated that the amorphous phase of crystalline polymers at temperature above its glass transition temperature differs markedly from low molecular weight liquids. Cavitation in polymers seemingly is not of a heterogeneous character, unlike in unpurified low molecular weight liquids. The most probable reasons are: confinements of amorphous layers between crystalline lamellae and macromolecular chain entanglements, the factors that are absent in low molecular weight liquids. |
