Polymer Classification: Stereospecificity01:26

Polymer Classification: Stereospecificity

3.3K
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...

Polymers: Molecular Weight Distribution01:10

Polymers: Molecular Weight Distribution

5.0K
For any given polymer, the weight average molecular weight (Mw) is higher than, if not equal to, the number average molecular weight (Mn). The only situation in which the weight average molecular weight and the number average molecular weight are equal is when a polymer consists only of chains with equal molecular weight. However, this never happens in a synthetic polymer, since it is difficult to control the polymerization process up to a molecular level with accuracy to a hundred percent.

Polymer Classification: Crystallinity

4.1K
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...

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Step-Growth Polymerization: Overview

4.5K
Step-growth or condensation polymerization is a stepwise reaction of bi or multifunctional monomers to form long-chain polymers. As all the monomers are reactive, most of the monomers are consumed at the early stages of the reaction to form small chains of reactive oligomers, which then combine to form long polymer chains in the late stages. Hence, the reaction has to proceed for a long time to achieve high molecular weight polymers.
Many natural and synthetic polymers are produced by...

Area of Science:

  • Polymer Physics
  • Computational Chemistry
  • Materials Science

Background:

  • Continuum polymer models are essential for simulating polymer behavior.
  • Excluded-volume interactions significantly influence polymer chain conformation and dynamics.
  • Understanding polymer behavior under varying conditions is crucial for materials design and biological applications.

Purpose of the Study:

  • To investigate three distinct continuum polymer models with tunable excluded-volume interactions.
  • To identify conditions for optimal polymer model behavior, characterized by asymptotic long-chain properties in shorter chains.
  • To explore the applicability of these models to double-stranded DNA and good-solvent polymer behavior.

Main Methods:

  • Development and analysis of three continuum polymer models: thick self-avoiding chains, generalized tangent hard-sphere, and generalized Kremer-Grest models.
  • Utilizing a tunable parameter 'r' to control the strength of excluded-volume interactions.
  • Investigating topological and dynamical properties, particularly for the thick self-avoiding chains model.

Main Results:

  • A specific parameter value ([Formula: see text]) was identified where all three models exhibit optimal behavior, showing asymptotic long-chain characteristics with shorter chains.
  • For other parameter values ([Formula: see text]), a two-parameter model effectively describes polymer behavior, including thermal crossover near the theta (θ) point.
  • The thick self-avoiding chains model, preventing bond crossing, is suitable for topological and dynamical studies.

Conclusions:

  • The study identifies an optimal parameter regime for continuum polymer models, enhancing simulation efficiency and applicability.
  • The findings provide insights into the conditions under which double-stranded DNA can be accurately modeled as a good-solvent polymer.
  • The developed models offer a versatile framework for studying polymer physics, topological properties, and DNA behavior.
