    摘要： There is disclosed an improved complex coacervation process for microencapsulation of core ingredients that are partially soluble in the microcapsule walls wherein the core ingredient is first mixed with a coacervation adjacent prior to forming a first colloidal emulsion of core ingredient, and, after combining the first emulsion with a second colloidal solution and cooling to cause gelation, a water-soluble wax derivative is added. No pH adjustment or dilution is necessary, and very high yields of non-agglomerated microcapsules are obtained, both in terms of quantity of microcapsules and content of core ingredient. When deet is the core ingredient there is obtained a long-lasting mosquito repellent.

    摘要： A device for the controlled continuous administration of an active agent to an environment of use is disclosed. The device comprises a body of erodible agent release rate controlling material containing an agent dispersed therethrough; the rate controlling material is a hydrophobic poly(carboxylic acid) having one ionizable carboxylic hydrogen for each 8 to 12 carbon atoms, which material erodes at a controlled and continuous rate over a prolonged period of time in response to the environment by a process of carboxylic hydrogen ionization, thereby releasing the dispersed agent at a controlled rate over a prolonged period of time.

    摘要： A process for polypropylene manufacturing, including treating a vent stream from the polymerization reactor, to recover propylene for return to the reactor. The process involves using a gas separation membrane to separate propylene from propane in the reactor vent stream. The membrane separation step results in a residue stream typically containing as much as 30% propane or more, which is vented from the polymerization process, and a permeate stream containing 95% or less propylene, which is recirculated to the polymerization reactor.
