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 (dart impact strength and tear strength of film, top load of a bottle, etc.) 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, etc. Headline... alles anzeigen expand_more
