Patent number: 7737217Abstract: The present invention relates to a method of making a ready-to-press agglomerated powder mixture by wet milling a powder mixture containing binder and spray drying said slurry to an agglomerated powder useful for making cutting tools for metal machining, tools for rock drilling and wear parts. If the binder is a baroplastic polymer having a pressure induced transformation from hard to soft well developed agglomerates with good flow properties and good plasticity are obtained. The hard property of the binder is used at normal pressures, during handling of the spray-dried powder and in the green body, whereas the softer properties are used at higher pressures during the pressing of the material when the pressure exceeds from about 10 to about 50 MPa.Type: GrantFiled: May 25, 2007Date of Patent: June 15, 2010Assignee: Sandvik Intellectual Property ABInventors: Annika Kauppi, Ulf Jutterström

Publication number: 20100093955Abstract: The present invention relates to a photoreactive polymer that comprises a multi-cyclic compound in a main chain, and a polymerization method thereof. Since the photoreactive polymer according to the present invention comprises a multi-cyclic compound having a high glass transition temperature as a main chain, the thermal stability is excellent, and since the mobility of the main chain is relatively high as compared to that of an additional polymer, a photoreactive group can be freely moved in the main chain of the polymer. Accordingly, it is possible to overcome a slow photoreactive rate that is considered a disadvantage of a polymer material used to prepare an alignment film for known liquid crystal display devices.Type: ApplicationFiled: March 21, 2008Publication date: April 15, 2010Inventors: Dai-Seung Choi, Hye-Young Jung, Sung-Ho Chun, Heon Kim, Sung-Don Hong, Dong-Woo Yoo
