Resin-Solvent Mixtures

This article describes a mixture that has a more consistant viscosity, avoids formation of large agglomerates and gels, reduces mixing time and, therefore, polymer degradation.

A conventional practice is to combine a resin and solvent, elevate the temperature, and mix until the resin has dissolved. The resultant mixture can vary greatly from lot to lot even after long mixing times.

This problem can be avoided by gradually feeding resin into a preheated solvent contained in a reactor with the impeller turning as the resin is added.
