Abstract
The instant invention discloses a method for forming glass/polymer alloy or composite pellets of a uniform shape, and exhibiting an increased density and pellet integrity/strength. The pellets are formed by melt-blending and extruding a semi-molten strand of the glass/polymer alloy or composite and subsequently compressing and cutting the strand into pellets at a predetermined pelletizing temperature. The predetermined pelletizing temperature is that temperature at which the glass/polymer alloy or composite extruded strand is still semi-molten and deformable and at which the so-formed pellets will maintain the shape imparted to them.
