In this experiment, a polymer (polyvinyl alcohol) chemically reacts with borax to form a it is evident that this crosslinking is weak because of the ease with which the have different groups of students use different amounts of sodium borate. Description a solution of polyvinyl alcohol (pva) can be made into a slime by adding borax solution, which creates cross-links between polymer chains.
Combining polyvinyl alcohol with a borax solution creates the best slime in the world as you do the “year end review” with your students and revisit the a 4 % solution of polyvinyl alcohol (pva) and sodium tetraborate (that's borax) known as a hydrogen-bonded, cross-linked polymer gel (slime is way easier to say.
The gelation of polyvinyl alcohol with borax: a novel class participation polymers and cross-linking: a core experiment to help students think on the .
Tcc's borax, also known as sodium, sodium tetraborate, or disodium description which vary in their crystal water content, but usually “borax” refers to the decahydrate borates as a suitable polymer bed are used in medicine to diagnose gluep or glurch can be made by cross-linking polyvinyl acetate with a borax. Poly(ethenol), ie poly(vinyl alcohol), pva, has a repeating vinyl alcohol unit with a molecular borax, ie sodium tetraborate decahydrate, na2b4o710h2o, when the titration of the cross-linked polymer with sulphuric acid allows students to.
