These substances polymerize in the paper and result in the construction of a strengthening network. Cationic starch. To enhance the paper's strength, cationic starch is added to wet pulp in the manufacturing process. Starch has a similar chemical structure as the cellulose fibre of the pulp, and the surface of both the starch and fibre are ...
The recipe consists of pancake mix, puffed rice, Grape-Nuts cereal, instant coffee and water to mix it all together. Brown hot glue is added after they are baked to create the “chocolate chips”.
Polyvinyl acetate is also the raw material to make other polymers like: Polyvinyl alcohol −[HOCHCH 2]−: Polyvinyl acetate is partially or completely hydrolysed to give polyvinyl alcohol. This reversible saponification and esterification reaction was a strong hint for Hermann Staudinger in the formulation of his theory of macromolecules. [12]
