Abstract: Compositions for use in manufacturing a water-soluble tooling material are disclosed. The compositions include an organic binder material that is water-soluble, a melt processing aid capable of reducing the glass transition temperature of the organic binder, and an aggregate material. A method for forming a composite structure is similarly disclosed and involves production of a mandrel by depositing a particulate mixture, including the aggregate material, the binder, and the melt processing aid, into a mold and removing the mandrel from the mold. Once finished, the mandrel can be used in manufacturing polymer and/or composite components.

Abstract: Methods for synthesizing a water-soluble titanium-silicon complex by partial hydrolysis are disclosed herein. The titanium-silicon complex can be utilized to produce titanated solid oxide supports and titanated chromium supported catalysts. The titanated chromium supported catalysts subsequently can be used to polymerize olefins to produce, for example, ethylene based homopolymer L and copolymers.
