Abstract

1399142 Melt spinning compositions MONSANTO CO 1 Aug 1972 [2 Aug 1971] 40629/74 Divided out of 1399141 Heading B5B [Also in Division B1] The subject-matter is that of the parent Specification 1,399,141 but the claims relate to the process for adding an anti-static wax to a synthetic polymer in which the latter is supplied in particulate form to, and melted in, a heated screw extruder, the wax injected into the molten polymer and kneaded thereinto in a screw mixer having interrupted flights and the product metered through a spinneret to form a continuous filament.
