Oct 26, 2018 · Tacticity refers to the orderliness of succession of configurational repeating units in the main chain of a macromolecule [1]. This is an application of stereochemistry as it concerns …

Tacticity (from Greek: τακτικός, romanized: taktikos, "relating to arrangement or order") is the relative stereochemistry of adjacent chiral centers within a macromolecule. [1][better source …

Nov 21, 2023 · Learn about the tacticity of polymers and understand the classification of polymers on the basis of activity. Explore examples of polymerization processes. Updated: 11/21/2023

There are three tactic forms in polymers: atactic, isotactic, and syn-diotactic. Isotactic and syndiotactic polymers are both stereoregular and thus are crystallizable.

Polymers without configurational regularity are called atactic. Configurationally regular polymers can fonn crystalline stmctures, while atactic polymers are almost always amorjihous. Many …

ABSTRACT: Tacticity is one of the most important features of stereoregular polymers, with significant impact on morphology and on a variety of properties such as conformational, …

A good example is polystyrene (PS). If a special catalyst is used in its synthesis it is possible to obtain the syndiotactic version of this polymer, but most industrial polystyrene produced is atactic.

Oct 6, 2009 · Polypropylene is a great example of how tacticity has a dramatic effect on the physical properties of the polymer. Atactic polypropylene has little order in the polymer …

Jun 29, 2017 · Polymers can be classified according to their chemical composition, their physical properties, and their general application. For each of these three categories, name two …

Isotactic polypropylene (iPP) fibres were produced by melt spinning method with take-up speeds between 2500 m/min and 4250 m/min. The effect of production parameters on structural …
