Abstract
Official abstract text for this publication.
A method of first dissolving a conjugated polymer in a fluid followed by adding an agent to the fluid and evaporating the fluid to produce a solid sample. The solid sample is then ground to produce a fragmented solid sample. This is followed by performing solvent extraction on the fragmented solid sample at elevated temperature and pressure to produce a purified conjugated polymer in a solvent.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: dissolving a conjugated polymer in a solvent; adding an agent to the solvent and evaporating the solvent to produce a solid sample; grinding the solid sample to produce a fragmented solid sample; and performing a solvent extraction, at a temperature greater than 90° C., on the fragmented solid sample to produce a purified conjugated polymer in a solvent; wherein the agent is diatomaceous earth, silica gel, or sand.…
