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 are magnetic. b. They can be cut quickly with inexpensive tools. C. Their low melting points mean that they can be cast with low energy cost. d. They glow in the dark. e. They are fireproof

Solution

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