Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that liquid CO2 can dissolve certain plastics?

Yes. Liquid and supercritical carbon dioxide acts as a solvent capable of dissolving and plasticizing various polymers, such as polystyrene and polyetherimide.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked 4 Aug 2026

The analysis

The retrieved papers provide direct evidence that liquid and supercritical carbon dioxide can dissolve and be absorbed by various plastics like polystyrene and polyetherimide, supporting the claim without any contradictory evidence.
