Abstract

1,132,969. Extrusion-granulating polyamides. IMPERIAL CHEMICAL INDUSTRIES Ltd. 4 March, 1966 [21 Dec., 1964], No. 51896/64. Heading B5A. Molten polyamide is delivered from an autoclave 1 via a heated fan-tailed valve to a die 2 whose orifice is of modified slot form, see Fig. 1 (not reproduced), the extrudate proceeding to a granulator 6 via a water cooled drum 4 and rollers 5. Further cooling of the extrudate is effected by water sprays 3. Polyamides specifically mentioned are polycaprolactam and polyhexamethylene adipamide. An example is given, wherein the latter material is fed under nitrogen pressure from the autoclave to the die while at a temperature of 270-280‹ C. and is cooled to about 80‹ C.
