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