WebThe interaction between different process parameters was also investigated.Methods and results: The optimized process parameters resulted in production of nanoencapsulated paracetamol in L-polylactide with a mean diameter of approximately 300 nm at 120 bar, 30°C, and a polymer concentration of 16 ppm. WebIn the polymer blend method, the overall thermal and mechanical properties of the blend are inevitably reduced because the additives are often thermally unstable and mechanically weaker. An alternative is to engineer and design PEI oligomers with reduced molecular weights, melt viscosities, and thus energy consumption during processing.
