  • Publication number: 20220388918
    Abstract: This present disclosure relates to a solid, particulate, urea ammonium sulphate-based composition, further comprising one or more alkaline or alkaline-forming inorganic or organic compounds that are able to interact with ammonium sulphate, a urease inhibitor of the type phosphoric triamide, and a cation source comprising a cation selected from the group consisting of Fe2+, Fe3+, Mn2+, Zn2+, Cu+, Cu2+, Ni2+, Ag+, Pt2+, Ru2+, Co3+ and Cr3+. The invention further relates to a method for the manufacture of a solid, particulate urea ammonium sulphate-based composition comprising urea, ammonium sulphate, a urease inhibitor of the type phosphoric triamide, in particular N-(n-butyl) thiophosphoric triamide (nBTPT), one or more alkaline or alkaline-forming inorganic or organic compounds and a cation source. The product is in particular suitable for use as a fertilizer.

  • Patent number: 9725535
    Abstract: Novel catalyst compositions comprising three or more transition metals are effective in increasing catalyst efficiency, reducing polydispersity, and increasing uniformity in molecular weight distribution when used in olefin, and particularly, linear low density polyethylene (LLDPE), polymerizations. The resulting polymers may be used to form differentiated products including, for example, films that may exhibit improved optical and mechanical properties.

  • Publication number: 20110097564
    Abstract: The invention provides a film comprising at least three layers, one inner layer adjacent to two outer layers, and wherein at least one inner layer is formed from a composition comprising an ethylene-based polymer with a density greater than, or equal to, 0.945 g/cc or a cyclic olefin copolymer; and wherein each outer layer is, independently, formed from a composition comprising a propylene-based polymer; and wherein the at least one inner layer is less than, or equal to, 25 percent of the total film thickness.
