摘要： A thermoplastic molding composition having reduced gloss sensitivity and no unpleasant odor is produced from a graft copolymer and a thermoplastic polymer. The graft copolymer is produced from a soft elastomeric particulate graft base obtained by emulsion polymerization of a conjugated diene alone or with a small amount of a mono- ethylenically unsaturated monomer, using an inorganic radical generating substance and a limited amount of chain transfer agent, upon which is grafted a vinyl aromatic monomer and acrylonitrile and optionally another monoethylenically unsaturated monomer using an inorganic radical generating substance while the use of a chain transfer agent is excluded. The thermoplastic polymer is a copolymer of a vinyl aromatic monomer and acrylonitrile and optionally an additional monoethylenically unsaturated monomer. The thermoplastic molding composition has a low level of unpleasant odor coupled with reduced gloss sensitivity and good mechanical properties.

摘要： Granule surface contours include less than 10% concave locations, the remainder being convex, as determined by incident-light interference contrast spectroscopy. Independent claims are included for the following: (1) a method of manufacturing polymer granules comprising forcing a polymer melt through a nozzle into a cutting chamber flooded with coolant and dividing the polymer; (2) a method of manufacturing moldings, film or fibers; and (3) a method of quality control employing incident light interference contrast spectroscopy to measure and control concave inclusions in their surfaces. The interval between emerging from the nozzle and cutting to granules is less than 20 ms. The granules are cooled in liquid coolant to a temperature of 60-130[deg]C at a rate of 2-30[deg]C/s. Granule/coolant ratio is 0.03:1 to 0.12:1. Coolant is introduced into the chamber at a pressure of 1.1 bar. The quality control method, without consideration of granule surface curvature, determines ring-shaped reflections arising from concave locations, and the surface area they enclose. These areas are expressed as a ratio of the total observed surface area.

摘要： The extruder has one or more degassing openings which are fitted with either a woven metal wire mesh, a finely perforated plate or a slit screen. Water is extracted either partially or completely in the fluid state. At least one dewatering opening is located upstream in front of a first metering unit and another downstream from the latter. Meshes are held in a frame pressed against the openings and in particular are folded onto an opening or attached to the latter by a bayonet connection. A preferred extruder has twin screws and: a) one or more metering sections in which thermoplastic material containing water or another vaporizable fluid is fed into the barrel and one or more dewatering openings; b) a compression section for dewatering a thermoplastic and including a restrictor and a dewatering opening; c) a feed section in which further thermoplastic melt is added; d) a mixing, kneading and/or plasticizing section; e) a degassing section in which residual water is extracted as steam via a dewatering opening; f) a metering section. All dewatering openings are fitted with a woven mesh, fine perforated plate or slit screen. Initial thermoplastic components contain not more than90wt% and are mixed with additional components while degassing and dewatering. Independent claims are included for: a) a process for manufacturing thermoplastics in which thermoplastic materials are fed into the claimed equipment, degassed and then metered; b) use of a metal wire mesh, fine perforated plate and/or slit screen for covering a degassing and/or dewatering opening in the claimed extruder.
