Eder H. C. Ferreira and Guilhermino J. M. Fechine studied the healing phenomenon adapted to understand the miscibility of polymer blends. The discussions are based on the deformation mechanism of HDPE, UHMWPE and HDPE‐UHMWPE blends produced under different conditions. The image illustrates the correlation of the five stages of the healing phenomenon at the polymer‐polymer interphase with the processing, molding, and mechanical performance of polyethylene blends. The advances reported in this paper can contribute to understanding the mechanical performance of different systems formed by compatible polyethylene blends. DOI: 10.1002/app.49604

Eder HC Ferreira和Guilhermino JM Fechine研究了适合于理解聚合物共混物相容性的愈合现象。讨论基于在不同条件下生产的HDPE，UHMWPE和HDPE-UHMWPE共混物的变形机理。该图显示了聚合物-聚合物界面处愈合现象的五个阶段与聚乙烯共混物的加工，成型和机械性能之间的关系。本文报道的进展可有助于理解由相容的聚乙烯共混物形成的不同体系的机械性能。DOI：10.1002 / app.49604
