  • Patent number: 9068068
    Abstract: The present invention provides a polypropylene-based resin composition, which comprises of a) a polypropylene; b) an ethylene 1-octene copolymer in which r1r2<1 (herein, r1=k11/k12, r2=k22/k21, k11 is a growth reaction rate constant when ethylene is added to a growth chain in which an end active site is ethylene, k12 is a growth reaction rate constant when octene is added to a growth chain in which an end active site is ethylene, k22 is a growth reaction rate constant when octene is added to a growth chain in which an end active site is octene, and k21 is a growth reaction rate constant when ethylene is added to a growth chain in which an end active site is octene); and c) an inorganic filling agent, and a part for vehicles manufactured by using the same.

  • Patent number: 8748547
    Abstract: The present invention relates to an ethylene ?-olefin copolymer having a narrower molecular weight distribution, and a uniform distribution of comonomer. The ethylene ?-olefin copolymer according to the present invention has a uniform comonomer distribution and exhibits a lower density in the same comonomer content, unlike conventional ethylene copolymers having a random or blocky comonomer distribution.

  • Publication number: 20070184548
    Abstract: The invention relates to a device for carrying out of chemical or biological reactions with a reaction vessel receiving element for receiving a microtiter plate with several reaction vessels, wherein the reaction vessel receiving element has several recesses arranged in a regular pattern to receive the respective reaction vessels, a heating device for heating the reaction vessel receiving element, and a cooling device for cooling the reaction vessel. The invention is characterized by the fact that the reaction vessel receiving element is divided into several segments. The individual segments are thermally decoupled from one another, and each segment is assigned a heating device which may be actuated independently of the others. By means of the segmentation of the reaction vessel receiving element, it is possible for zones to be set and held at different temperatures.
