Features: This book focuses on polyolefins and their blends as the research subjects, comprehensively discussing the morphological development and structural changes of polyolefins and their blends during injection molding processing, as well as the relationship between morphology and performance. The book is divided into 6 chapters. Chapter 1 introduces the research progress and development trends of polyolefin injection molding technology and morphological control technology, as well as an overview of the fundamental issues of morphology, phase behavior, and crystallization of polymer blends under stress fields. Chapter 2 details the changes in the performance of several polyolefin blends under shear stress fields and their influencing factors, and analyzes the morphology and orientation structure of the blends. Chapter 3 discusses the effects of shear stress on the compatibility, phase separation, phase inversion, and micro morphology of blends. Chapter 4 explores the mechanical properties of HDPE/EVA crystalline/non-crystalline blends, clarifying the influence of molecular orientation, phase morphology, and interfacial interactions on mechanical properties. Chapter 5 systematically investigates the deformation of rubber particles caused by shear and the brittle-ductile-brittle transition in polyolefin toughening. Chapter 6 studies polyolefins with clear lamellar orientation, using "stepcycle" and stress relaxation to examine deformation characteristics, and combines structural changes during deformation to elucidate deformation mechanisms, clarifying the nature of fine necking and viscous forces, providing a theoretical foundation for material design and modification. This book can serve as a reference for researchers engaged in polymer molding processing, polymer blends, and composite materials, as well as related disciplines. It can also be used as a reference material for graduate students and senior undergraduate students in relevant fields at universities.
