单词	tacticity
释义	tacticity /takˈtɪsɪti / noun [mass noun] Chemistry The stereochemical arrangement of the units in the main chain of a polymer.The rate of hydrolysis depends not only on the tacticity of the polymer, but probably also on its configurational sequence statistics.... Metallocene catalysts allow for control of tacticity in polyolefins, making it possible to synthesize materials with a wide range of properties from a single monomer. This association explains strong dependencies of the statistical segment length on tacticity and temperature in the vicinity of the melting point.
