摘要： The present invention relates to a process for the production of a reinforced polyamide (rP) in an extruder. In this process, a first mixture (M1), a second mixture (M2) and a third mixture (M3) are added into the extruder, and subsequently at least one carbon material is added to obtain a carbon containing polymerizable mixture (cpM) in the extruder. This carbon containing polymerizable mixture (cpM) is polymerized and subsequently devolatilized to obtain the reinforced polyamide (rP). Furthermore, the present invention relates to the reinforced polyamide (rP) obtainable by the inventive process.

摘要： A molding material comprising a pellet group of at least 20 saponified ethylene-vinyl ester-based copolymer pellets, wherein at least 95% of the pellets have a surface that is substantially a single closed surface, and when a maximum outer diameter of a pellet is taken as a long diameter and a minimum diameter in a cross section having the greatest area among the cross sections perpendicular to the long diameter is taken as a short diameter, the average value of the long diameter/short diameter ratio of at least 20 pellets taken from the pellet group is 1.6 or less and the standard deviation of the long diameter/short diameter ratio of the at least 20 pellets is 0.13 or less.

摘要： A method of manufacturing bulked continuous carpet filament which, in various embodiments, comprises: (A) grinding recycled PET bottles into a group of flakes; (B) washing the flakes; (C) identifying and removing impurities, including impure flakes, from the group of flakes; (D) adding one or more color concentrates to the flakes; (E) passing the group of flakes through an MRS extruder while maintaining the pressure within the MRS portion of the MRS extruder below about 25 millibars; (F) passing the resulting polymer melt through at least one filter having a micron rating of less than about 50 microns; and (G) forming the recycled polymer into bulked continuous carpet filament that consists essentially of recycled PET.
