Conclusions

The form of the interface in the melting of a polymer in an extruder has been studied. It has been found that it differs considerably from right-angled, and melting of the polymer takes place over its entire curvolinear surface.

The three components of polymer melt velocity have been constructed: The change in these both over the cross-sectional area of the extruder screw and also along its length has been noted.

In the liquid phase of the polymer, an intense circulation of the melt takes place in the transverse plane of the screw channel.
