Abstract: | Porous films of high density polyethylene (HDPE) and its blends with oligomeric oxidized polyethylene (OxPE) were prepared. The effect of the additive on porous structure and mechanical properties was investigated. Degree of crystallinity, pore size distribution, specific surface, gas and liquid permeability were measured for permeable samples. Changes in porous structure and mechanical properties of the samples upon changes of additive content have been studied. It was established that oxidized PE additive is located in intercrystalline amorphous regions, and hinders pore formation. |
