Polypropylene (PP) is a typical polymorphic polymer with a-form, b-form, Iform, and mesomorphic smectic form modifications, and crystallizes into diverse morphologies. In this book, Chapter One comprehensively reviews the kinds of self-assembly b-nucleating agents and the manipulation strategies in the practical processing to control the crystal structure and prepare high-performance PP products. Chapter Two discusses the molecular structure at the cross-linking point of stereoregular isotactic polypropylene (i PP) and syndiotactic polypropylene (s PP) gels in comparison with the crystal formed in the solid state such as film. Chapter Three investigates the thermal insulation performance of polypropylene as thermal insulator for a solar air collector in comparison with coconut fibre. Chapter Four reviews the mechanical properties, crystallization and degradation of polypropylene due to nucleating agents, fillers and additives. Chapter Five examines polypropylene biodegradation. Chapter Six addresses the potential utilization of different lignocellulosic biomasses for the development of green materials based on polypropylene, with the objective to elucidate the possibility of using the bio based materials for various industrial applications.
