  • Patent number: 10626202
    Abstract: Monomodal copolymers of ethylene and molding compositions comprising such copolymers, wherein the copolymers have a density determined according to DIN EN ISO 1183-1, variant A in the range from 0.938 to 0.944 g/cm3, a melt index MFR21 determined according to ISO 1133 at 190° C. under a load of 21.6 kg in the range from 12 to 17 g/10 min, a weight average molar mass Mw in the range from 140 000 g/mol to 330 000 g/mol, a polydispersity Mw/Mn in the range from 9 to 17, and a content of comonomer side chains per 1000 carbon atoms Cx equal to or above a value defined via equation (I) Cx=128.7?134.62×d?, wherein d? is the numerical value of the density of the copolymer in g/cm3, the use of the copolymers for producing injection-molded articles, as well as injection-molded articles comprising the copolymers, and process for the preparation of such monomodal copolymers.
    Type: Grant

  • Patent number: 7842905
    Abstract: This invention relates to a method and a device for the thermal treatment of substrates in which the substrates are held in contact with or a small distance away from a heating plate, which is heated by a plurality of separately controllable heating elements on the side of the heating plate facing away from the substrate, the heating plate being surrounded, at least in its plane, by a frame spaced apart therefrom, and gas being conveyed, in a controlled manner, through a gap between the frame and at least one edge of the heating plate.
    Type: Grant
