For engineers engaged in plastic modification，Twin Screw Extrusion Machine（TSE）is one of the most familiar equipments. We can obtain specific phase structure and functionalized polymer components by formula design and the optimization of process parameters. However, what happened during the processing in TSE maybe still a “mystery”.

And recently, we feel much honored to have invited Professor Sakai, who is a famous specialist in plastic modification industry, to reveal the “mystery” of phase evolution during the processing in TSE. And we also talked about the graft copolymerization of polyolefin by melt-blending process used with TSE.

In the morning, Professor Sakai used almost 3 hours to reveal the phase evolution during the processing in TSE. Large amounts of cases were used to reveal the
