Such charts are particularly important for polymers [4] as they are often not compatible with common chemical reagents; this may even depend on how the polymers have been processed. [5] For example, 3-D printing polymer tools used for chemical experiments must be chosen to ensure chemical compatibility with care. [6]
An advantage to solvent bonding versus other polymer joining methods is that bonding generally occurs below the glass transition temperature of the polymer. [2] [3] Solvent bonding differs from adhesive bonding, because the solvent does not become a permanent addition to the joined substrate. [4] Solvent bonding differs from other plastic ...
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
Another application of polymer solutions includes the manufacture of fibers by wet or dry spinning or plastic films. Disadvantages of solution polymerization are decrease of monomer and initiator concentration leading to reduction of reaction rate, lower volume utilization of reactor, additional cost of the process related to solvent recycling ...
In polymer chemistry, compatibilization is the addition of a substance to an immiscible blend of polymers that will increase their stability. Polymer blends are typically described by coarse, unstable phase morphologies; this results in poor mechanical properties. Compatibilizing the system will make a more stable and better blended phase ...
Flory–Huggins solution theory is a lattice model of the thermodynamics of polymer solutions which takes account of the great dissimilarity in molecular sizes in adapting the usual expression for the entropy of mixing. The result is an equation for the Gibbs free energy change for mixing a polymer with a solvent. Although it makes simplifying ...
The nearer two molecules are in this three-dimensional space, the more likely they are to dissolve into each other. To determine if the parameters of two molecules (usually a solvent and a polymer) are within range, a value called interaction radius is given to the substance being dissolved. This value determines the radius of the sphere in ...
Lightly crosslinked refers to the lightly woven polymer portion of the scavenger. This type of resin becomes swollen in a particular solvent, allowing an impurity to react with a specified functional group. In many times single solvents are not sufficient to expand the resin, in which case a second solvent must be added.
