Final answer:
Nathaniel Wyeth's plastic soft drink bottles are made from Polyethylene terephthalate (PET), which is also used for textiles as polyester and constitutes 30% of the plastics market for bottle production.
Step-by-step explanation:
Nathaniel Wyeth developed plastic soft drink bottles, and they are made from the polymer Polyethylene terephthalate (PET). PET is the most common thermoplastic polymer resin of the polyester family, and it's used in a variety of applications including fibers for clothing, containers for liquids and foods, thermoforming for manufacturing, and, when combined with glass fiber, for engineering resins. The widespread use of PET for bottle production accounts for about 30% of global demand, and it is a major component of the plastics market.
