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.
