Application of Polymers for Chemical Enhanced Oil Recovery: A Review

Polymers, 2022
Polymers play a significant role in enhanced oil recovery (EOR) due to their viscoelastic properties and macromolecular structure. Herein, the mechanisms of the application of polymeric materials for enhanced oil recovery are elucidated.

Polymers for 3D Printing and Customized Additive Manufacturing

Chemical Reviews, 2017
Additive manufacturing (AM) alias 3D printing translates computer-aided design (CAD) virtual 3D models into physical objects. By digital slicing of CAD, 3D scan, or tomography data, AM builds objects layer by layer without the need for molds or machining.

Synthesis of oligo- and polythiophenes in zeolite hosts [PDF]

, 1993
Oligomers and polymers of thiophene derivatives were synthesized in the channels of zeolite Y and mordenite. Intrazeolite oxidation of monomers such as thiophene , 3- methylthiophene , and bithiophene by Fe(lll) or Cu(ll) ions results in formation of ...

Stretching of polymers in a turbulent environment [PDF]

, 2002
The interaction of polymers with small-scale velocity gradients can trigger a coil-stretch transition in the polymers. We analyze this transition within a direct numerical simulation of shear turbulence with an Oldroyd-B model for the polymer.

Linear Rheological Response of a Series of Densely Branched Brush Polymers [PDF]

, 2011
We have examined the linear rheological responses of a series of welldefined, dense, regularly branched brush polymers. These narrow molecular weight distribution brush polymers had polynorobornene backbones with degrees of polymerization (DP) of 200 ...
