Homework Help: Gr.12 Chem - PLEASE CHECK MY ANSWER

Posted by Heidi on Wednesday, May 28, 2008 at 2:40pm.

Hi, Im learning about polymers. I did a lab to make slime where I mixed PVA glue & water. I then added borax to some water in another container, and the poured off the water from the wet borax. I then added the borax to the glue/water solution. I have to make a procedure that will produce a more runny slime, so I figured that I should add less water TO THE BORAX, because a condensation polymer is happening( I think????) and they become stronger with more intermolecular bonds (formed form the H atoms in the water)...Is my thinking right?
