The book provides a bridge between the meaning of engineering end-use parameters of polyethylene resins (HDPE, LDPE, LLDPE, VLDPE) and their molecular characteristics. The main goal is to translate common end-use characteristics of the resins (melt index, density, melting point) or properties of standard items manufactured from the resins (e.g., dart impact strength and tear strength of film, top load of a bottle) into the universal language of the polymer science, average molecular weight and molecular weight distribution of a polymer, composition and a statistical description of a copolymer, parameters of the stress-strain curve of a semi-crystalline material.
