Polyvinyl Alcohol Activities

Polyvinyl alcohol (PVA) is the world’s largest volume, synthetic, water soluble polymer. PVA is nonhazardous and is used in many adhesives, films and elastomers. Its most popular use in schools is in the preparation of “slime.” PVA is a polymer with a repeating vinyl alcohol unit and its molecular weight can range from 25,000 to 300,000.
