Summary
Stereoirregular polymers can crystallize by adopting specific chain structures, enabling crystalline packing. This review guides the design of such polymers without complex synthesis, impacting material properties.
Area of Science:
- Polymer Science
- Materials Science
- Crystallography
Background:
- Crystallization is a natural phase transition influencing material properties.
- Synthetic polymers typically exhibit partial ordering due to thermodynamic and kinetic factors.
- Stereo- and regioregular polymers usually crystallize, while atactic polymers are amorphous.
Purpose of the Study:
- To explore the structural requirements for crystallization in atactic polymers.
- To provide strategies for designing crystalline polymers without strict stereocontrol.
- To understand the relationship between polymer structure and induced crystallization.
Main Methods:
- Review of existing literature on polymer crystallization.
- Analysis of structural features enabling chain packing in irregular polymers.
- Identification of design principles for synthesizing crystalline atactic polymers.
Main Results:
- Atactic polymers can crystallize if their irregular chains possess specific structural features for packing.
- Crystallinity can be induced in stereoirregular polymers through tailored structural design.
- Understanding structure-property relationships is key to controlling polymer crystallization.
Conclusions:
- Specific structural attributes in atactic polymers can overcome amorphous limitations, enabling crystallization.
- This work offers a framework for designing polymers with controllable crystallinity.
- Researchers can achieve polymer crystallinity without demanding precise stereochemical synthesis.

4.3K
Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

3.4K
Polymerization generates chiral centers along the entire backbone of a polymer chain. Accordingly, the stereochemistry of the substituent group has a significant effect on polymer properties. Polymers formed from monosubstituted alkene monomers feature chiral carbons at every alternate position in the polymer backbone. Relative to the predominant orientation of substituents at the adjacent chiral carbons, the polymer can exist in three different configurations: isotactic, syndiotactic, and...

01:25Crystal Growth: Principles of Crystallization
6.0K
Crystallization is a phase transformation process in which crystals are precipitated from a supersaturated solution or formed from other sources. During crystallization, atoms or molecules arrange themselves into a well-defined, rigid crystal lattice to minimize energy.
Initiating crystallization involves manipulating the concentration of the solute and the temperature of the solution. Since crystal growth occurs when the ratio of concentration and solubility of the solute in the solvent...

00:57Cationic Chain-Growth Polymerization: Mechanism
3.1K
The cationic polymerization mechanism consists of three steps: initiation, propagation, and termination. In the initiation step of the polymerization process, the π bond of a monomer gets protonated by the Lewis acid catalyst, which is formed from boron trifluoride and water. The protonation of the π bond generates a carbocation stabilized by the electron‐donating group. In the propagation step, the π bond of the second monomer acts as a nucleophile and attacks the...

01:10Recrystallization: Solid–Solution Equilibria
4.7K
Recrystallization is a purification technique used to separate impurities from solid compounds. In this technique, no chemical reactions occur. Instead, it exploits physical properties only, specifically, the solubility differences between the desired compound and impurities, either at a single temperature or at different temperatures, and under other selected conditions. The solid-solution equilibrium (solubility equilibrium) of each component in the solution represents a binary phase...

01:20Anionic Chain-Growth Polymerization: Overview
2.8K
The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth polymerization. Anionic polymerization gets initiated by a strong nucleophile such as an organolithium or a Grignard reagent. The most commonly used initiator for anionic polymerization is butyl lithium. Monomers involved in anionic polymerization must possess a vinyl group bonded to one or two electron-withdrawing groups. For instance,...
