What is cross-linking in a polymer?

1

Select the true statments

Metals are poor conductors of electricity because they hold their electrons tightly.

Polymers with a lot of cross-linking are usually rigid.

Ionic compounds tend to be brittle.

Metals tend to be brittle.

A substance with hydrogen bonding usually has higher viscosity than a similar molecule without hydrogen bonding.

A nonpolar substance with weak dispersion forces tends to have high surface tension.
