The low strength of the secondary bonds in polymer materials

The low strength of the secondary bonds in polymer materials can be an advantage in some applications because: (Choose all that apply) a. They glow in the dark. is, They are fireproof C. Their low melting points mean that they can be cast with low energy cost. d. They are magnetic. e. They can be cut quickly with inexpensive tools.

Solution

the correct option is option C. weak bonds have lower force of attraction beteen the molecules of polymer and can be easily broken down with very low energy. they posses very low melting point and this property they can be cast with low energy.
