Making more polymer solutions… And heating polymer emulsions
This week, we made more polymer solutions, this time with 5% concentration of polymer, using the same method as before.
We also tested the stability of polymer emulsions by heating and mixing them in an oil bath for 2 hours at room temperature，40°C，50°C，60°C and 70°C. After heating and mixing, the emulsions were then left alone and the time taken for each polymer emulsion to phase was noted down… Some of the emulsions took almost 3 hours to separate into phases!
