In this work, we discuss the dynamic viscoelasticity of three novolac resins with different molar masses and methylene linkage patterns (para–para′, ortho–ortho′ and ortho–para′ methylene linkages) to ...
The Mark–Houwink plot can be used to study polymer structure in solution as it clearly shows the relationship between structure and molecular weight (MW), with excellent sensitivity. The molecular ...

Biotech Fluidics AB announce working with Polymer Char (Valencia, Spain), a leading manufacturer of analytical systems for the polymer industry, to incorporate an optimized DeGASi® degasser in their ...
The characterization of polymers in the plastics industry relies heavily on the measurement of viscosity in polymer solutions. This fundamental tool is essential for assessing newly polymerized ...
Viscosity, or a fluid’s resistance to flow, is independent of the rate of shear or shear stress, at a given temperature, for Newtonian fluids. Non-Newtonian fluids such as polymer solutions often ...
Microcrystalline cellulose is a very versatile substance used in the lab. As the name implies, microcrystalline cellulose is basically cellulose and is typically derived from high-quality wood pulp.
While demand is strong for polyethylene terephthalate (PET) bottle flakes, that is not yet the case for PET flakes made from thermoformed containers. In the U.S., roughly 15 percent of PET ...
