  • Patent number: 8901260
    Abstract: An interpolymer of ethylene and at least one alpha-olefin is claimed, wherein the ethylene interpolymer is characterized as having an average Mv and a valley temperature between the interpolymer and high crystalline fraction, Thc, such that the average Mv for a fraction above Thc from ATREF divided by average Mv of the whole polymer from ATREF (Mhc/Mp) is less then about 1.95 and wherein the interpolymer has a CDBI of less than 60%. The interpolymer of ethylene and at least one alpha-olefin can also be characterized as having a high density (HD) fraction and an overall density such that % HD fraction<?2733.3+2988.7x+144111.5 (x?0.92325)2 where x is the density in grams/cubic centimeter. Fabricated articles comprising the novel interpolymers are also disclosed.
    Type: Grant

  • Patent number: 4619669
    Abstract: A method is disclosed for upgrading run-of-the-mine (ROM) lignites to remove the gangue (clays, rock etc.) which form ash when the lignite is burned. The unique features of the process, a combination of unit operations in a specified sequence, result in less loss of combustible fuel value without hydrodegradation (the production of a large volume of fines) normally associated with contact of the lignite with water as in pipeline transport of lignite.
