Day 14 – 20 Vinylimidazole Sulphobetaine

Very late post for day 14.

Most of the data is in the log book.
The hydrogel has shrank turned brittle but has a glass like state indicating successful polymerisation.

Texture:
Very sticky like taffy when exposed to water.

Day before drying via dessication for 14 days

After dessication / Monomer and Polymer

Day 13: Polymerization 1-Vinyl-3-(3-sulphopropyl)imidazolium hydroxide inner salt

Day 13:

Success, managed to get the initator to work with the monomer at 60 degrees C without making the test tube explode during the nitrogen gas flussing step.

But with success there is slight failure where I could not open the top for the test tube glass device. Cooking it for another day to see if the cap will loosen. Probably use plyers if it doesnt work out tomorrow.
