tacticitythe
Tacticity refers to the stereochemical arrangement of atoms or groups of atoms in a polymer chain. Specifically, it describes the relative configuration of chiral centers or stereogenic units along the polymer backbone. This arrangement significantly influences the physical properties of the polymer, such as its melting point, crystallinity, solubility, and mechanical strength.
In polymers formed from monomers with a chiral center, tacticity is classified into three main types: isotactic,
The tacticity of a polymer is determined during the polymerization process, particularly by the type of catalyst
