Tacticity - Wikipedia
网页A ball-and-stick model of syndiotactic polypropylene. Tacticity (from Greek: τακτικός, romanized: taktikos, "relating to arrangement or order") is the relative stereochemistry of adjacent chiral centers within a macromolecule. [1] The practical significance of tacticity rests on the effects on the physical properties of the polymer.
Isotactic Definition & Meaning - Merriam-Webster
网页The meaning of ISOTACTIC is having or relating to a stereochemical regularity of structure in the repeating units of a polymer.
Isotactic - Vocab, Definition, and Must Know Facts - Fiveable
网页Definition. In the context of synthetic polymers, isotactic refers to a polymer configuration where all substituents (like methyl groups) are positioned on the same side of the polymer chain. This arrangement results from a stereospecific polymerization process, leading to materials with distinct physical properties.
What is the Difference Between Atactic Isotactic and Syndiotactic …
网页Isotactic polymers have their substituents arranged in a regular manner, all on one side of the backbone, making them semi-crystalline. Syndiotactic polymers have their substituents arranged in a regular, alternating pattern around the backbone, making them crystalline.
Isotactic Polymers - Vocab, Definition, and Must Know Facts
网页Isotactic polymers are a type of stereoisomeric polymer where all the substituent groups are aligned on the same side of the polymer chain. This uniform arrangement leads to unique physical properties, making them distinct from other polymer configurations such as syndiotactic or atactic forms.
29.5: Correlation of Polymer Properties with Structure
网页Isotactic polypropene is a hard, clear, strong crystalline polymer that melts at 175o 175 o. It is practically insoluble in all organic solvents at room temperature, but will dissolve to the extent of a few percent in hot 1,1,2,2-tetrachloroethane.
Isotactic polymer | chemistry | Britannica
网页Isotactic and syndiotactic polymers are referred to as stereoregular—that is, polymers having an ordered arrangement of pendant groups along the chain. A polymer with a random orientation of groups is said to be atactic.
Isotactic Polymer - an overview | ScienceDirect Topics
网页An isotactic polymer that contains two chiral or prochiral atoms with defined stereochemistry in the main chain of the configurational base unit. From: Comprehensive Polymer Science and Supplements, 1989
ISOTACTIC Definition & Meaning | Dictionary.com
网页Isotactic definition: (of a polymer) having the same configuration at successive, regularly spaced positions along the chain.. See examples of ISOTACTIC used in a sentence.
Isotactic - Learn Chemistry Online | ChemistryScore
网页Isotactic Definition: A polymer in which the repeating units contain chirality centers which all have the same configuration. Isotactic Explained: Polymers that have an ordered arrangement in a chain. Having identical steric configurations of the groups on each asymmetric carbon atom on the chain.
