Explanation
It is also called short range structure or the primary structure of the primary structure of polymers. It mainly refers to the chemical composition, molecular configuration, chain branching and crosslinking structure of the structural unit of macromolecule, and the composition and sequence distribution of copolymer. short-range structure fundamentally affects the physical and chemical properties of macromolecule, and most directly affects the properties of macromolecule. Some properties that are greatly affected include reactivity, solubility, density, viscosity, adhesion, glass transition temperature, etc.
