摘要

LLDPE和EBC共混物的性能可能引起工业和研究人员的兴趣。因此，LLDPE/EBC共混物采用熔体混合工艺以不同的比例制备。拉伸强度和杨氏模量随着LLDPE含量的增加而增加，这是由于结晶度的增加，而伸长率随着EBC含量的增加而增加，这是由于非晶度的增加。经电子束辐照的LLDPE含量高的共混物凝胶含量高，交联度高，机械强度好，而未交联和交联的ebc含量高的共混物收缩性好。这种吸引人的性能组合显示了交联共混物在各种应用中的潜力。

Effect of electron beam irradiation on the mechanical, dynamic mechanical, heat-shrinkable and morphological properties of linear low-density polyethylene (LLDPE)/ethylene butene copolymer (EBC) blends

The properties of LLDPE and EBC blends may be interesting to both industries and researchers. Hence LLDPE/EBC blends are prepared in varying ratios using melt mixing process. Tensile strength and Young's modulus are increased with LLDPE content due to higher crystallinity, while % elongation improves with higher EBC content due to higher amorphousness. Electron beam irradiated blends with more LLDPE show greater gel content, i.e., higher degree of crosslinking and better mechanical strength, while EBC-rich blends, un-crosslinked and crosslinked, exhibit better shrinkability. This attractive combination of properties demonstrates the potential of crosslinked blends for various applications.
