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]
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 ...
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 ...
This Wikipedia page provides a comprehensive list of boiling and freezing points for various solvents.
2-Ethylhexyl acrylate polymerizes easily. The polymerization can be initiated by light, peroxides, heat, or contaminants.It can react violently when combined with strong oxidants and can form explosive mixtures with air at temperatures above 82 °C (180 °F). [2]
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 ...
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 ...
In a polymer solution, a theta solvent (or θ solvent) is a solvent in which polymer coils act like ideal chains, assuming exactly their random walk coil dimensions. [ clarification needed ] Therefore, the Mark–Houwink equation exponent is 1 / 2 {\displaystyle 1/2} in a theta solvent.
