Polyethylene is a polymer that is flexible and often used to make clear plastic wrap. How can this polymer be changed to make it less flexible, stronger, and harder? (1 point)

Question

1. Changing the covalent bonds to ionic bonds, which are stronger.
2. Adding larger carbon atoms in between the layers to make them more stable.
3. Cross-linking the layers of polyethylene using covalent bonds.
4. Shortening the length, the polymer so that it cannot bend as much.

Answer 1

3. Cross-linking the layers of polyethylene using covalent bonds.
