    摘要： Compositions and methods for stabilizing biomolecules are disclosed. Specifically, the compositions include novel homopolymers or copolymers containing trehalose side chains conjugated to biomolecules. When such homopolymers or copolymers are placed in close proximity to biomolecules, such as proteins, the homopolymers or copolymers protect and/or stabilize the biomolecule. The compositions and methods may be suitable for use in various industries such as healthcare (pharmaceuticals), molecular biology, biofuels, paper, personal care, detergent, photographic, rubber, brewing, dairy and food processing industries.

    摘要： A composition including polyalphaolefins that function as drag reducing agents and a process for the preparation of polyalphaolefins that function as drag reducing agents are disclosed. The process includes contacting alpha olefin monomers with a catalyst system, which includes a catalyst and an activator (co-catalyst) in a reactant mixture. The catalyst is a transition metal catalyst, preferably titanium trichloride, and the co-catalyst may include an alkylaluminoxane, alone or in combination, with a dialkylaluminum halide or a halohydrocarbon. The polymerization of the alpha olefin monomers produces a non-crystalline, ultra-high molecular weight polyalphaolefin having an inherent viscosity of at least 10 dL/g. The addition of the alkylaluminoxane during the polymerization process provides for a non-crystalline, ultra-high molecular weight polyalphaolefin and a more uniform molecular weight distribution of the resulting polyalphaolefin, thereby creating a drag reducing agent superior to known drag reducing agents. A process for forming a drag reducing agent comprising a non-crystalline, ultra-high molecular weight polyalphaolefin having an inherent viscosity of about at least 10 dL/g and a process for reducing drag in a conduit are also disclosed.
