This cannot be done. If a plastic dissolves in an acid, the polymer will have been disrupted and the plastic will not be reconstituted. The same goes for basic dissolution.

The best way to soften plastics, and then later have them harden again is to melt them.
- Mild heat leaves the polymer chains intact, but temporarily mobilises them.
- Only works for thermoplastics...
