Molecular Weight of Step-Growth Polymers01:08

Molecular Weight of Step-Growth Polymers

Step growth polymerization involves bi or multifunctional monomers. Bifunctional monomers react to form linear step growth polymers, whereas multifunctional monomers react to form non-linear or branched polymers.
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
The extent of the...

Summary
This summary is machine-generated.

In simple shear flow, bidisperse bubbles segregate by size, with larger bubbles moving centrally and smaller ones towards walls above critical thresholds. This size-driven segregation in bubble systems is accurately predicted by an adapted model.

Area of Science:

  • Fluid dynamics
  • Soft matter physics
  • Colloid science

Background:

  • Understanding bubble behavior in shear flow is crucial for industrial processes.
  • Bubble segregation in emulsions and foams is a complex phenomenon driven by various forces.
  • Existing models often simplify bubble interactions and size distributions.

Purpose of the Study:

  • To investigate the size-segregation of bidisperse and polydisperse bubbles under simple shear.
  • To develop and validate a predictive model for bubble spatial distribution in a Couette device.
  • To understand the interplay between bubble size, shear rate, and bubble-bubble interactions.

Main Methods:

  • Experiments using a Couette device to apply simple shear to bubble monolayers.
  • Systematic variation of shear rate, bubble size ratio, and area fraction.
  • Adaptation of a model for monodisperse emulsions to account for bidispersity and polydispersity.

Main Results:

  • Observed size segregation: larger bubbles migrate to the center, smaller bubbles to the walls above critical shear rates and size ratios.
  • The spatial distribution of larger bubbles flattens with increasing area fraction.
  • The adapted model accurately predicts the observed bubble distributions.

Conclusions:

  • Bubble size segregation in shear flow is governed by a balance between wall migration and shear-induced diffusion.
  • Bubble-bubble interactions in dense foams significantly influence segregation dynamics.
  • The effective capillary number, accounting for bubble deformation, is key to the model's predictive accuracy.
