Abstract: PROBLEM TO BE SOLVED: To determine variation in the color of a molten plastic quickly and accurately by introducing a light through a light emitting duct and a sensor head to a molten molding material and transmitting the light reflected therefrom to a spectrometer through a light receiving duct. SOLUTION: Uncolored plastic granules 1 and granules 2 containing a large quantity of coloring agent are fed an extruder 4 having two shafts turning simultaneously at same speed while meshing tightly and heated up to a temperature higher than the melting point while being mixed uniformly. An extrusion molding is delivered to a catcher 5. At the end of the extruder 4 mixed with the free ends of a light emitting duct 7 and a light receiving duct 9, a sensor head 6 projects into the extruder 4 through screw engagement. The light emitting duct 7 is coupled with a light source 8 and the light receiving duct 9 is coupled with a spectrometer 10. Pulse from the spectrometer 10 is delivered to an analyzer 11.

Abstract: The invention relates to a shock-resistant polystyrene with a maximum caoutchouc content of 10 wt.- %. The polystyrene has a melt-volume flow rate MVR (200 DEG C/5 kg, measured according to ISO 1133) in the range of 8 to 12 cm /10 min and a Charpy impact test value (according to ISO 179/1eA, notch milled) in the range of 16 to 20 kJ/m .
