- •
A new approach is designed for improving in situ compatibilization with scCO2.
- •
The approach is more effective in improving dispersion and mechanical properties.
- •
ScCO2 promotes formation of interfacial modifiers for PP/PS blends.
- •
ScCO2 improves dispersion through viscosity change of PP/PS blends.
- •
Two functions of scCO2 improve phase dispersion for in situ compatibilization.
