제목 Influence of crystallinity on the mechanical properties of XLPE/POE and LDPE/POE blend systems
초록 Crosslinked and noncrosslinked linear low density polyehtylene (XLPE/LDPE) with different contents of polyolefin elastomer (POE) has been evaluated. Influence of POE and crosslinking on the mechanical properties of LDPE/POE and XLPE/POE blends has been investigated using dynamic mechanical analysis (DMA). The storage modulus and Tg was found that sensitively depend on crystallinity. The storage modulus and Tg was decrease with increase of POE contents. This results were due to POE with many branches reduce the crystallinity of blends. The results showed a new finding about decrease in Tg as a consequence of the 'chemical crosslinking' of blends. This was explained by reduction of crystallinity, which chain packing was hinderend because of POE branches and free volume was increased.
