Investigating the effectivness of PVA and PVAc as base polymers In the production of a polymer ball. Introduction A monomer refers to a specific group of atoms that from a molecular unit. When monomers are strung together like a long chain they form polymers. A good analogy of polymers‚ would be long connections of chains which become tangled like a bunch of spaghetti in a pot. The reason for experimenting with‚ and understanding polymers is because they play such a major roll and are found
