Abstract:
Parallel semi-continuous or continuous reactors are disclosed. The parallel reactors preferably comprise four or more reaction vessels. The reaction vessels are preferably small volume reaction vessels, preferably pressure reaction vessels, and/or preferably integral with a common reactor block. The reaction vessels can comprise shaft-driven stirrers. At least two, preferably at least three or at least four liquid feed lines can provide selective fluid communication between each of the reaction vessels and one or more liquid reagent sources. Additional features, suitable in connection with parallel reactors or with single reaction vessels are also disclosed.
Abstract:
A method and system for researching and developing and/or optimizing new catalysts and polymers in a combinatorial manner is disclosed. The method begins with starting components or a ligand library and provides methods of creating catalyst or product libraries, which are then tested in a reaction of interest. The system uses methods of robotic handling for moving libraries from station to station. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial catalyst libraries.
Abstract:
A method and apparatus (10) for reacting a plurality of different mixtures in parallel in a semi-batch or continuous mode is provided. Each reaction is contained within a reactor vessel (102), the reactor vessels (102) combined into a reactor block (100). Reactant(s) to be added during the reaction are kept in a header barrel (202), which has a plunger (402) to feed reactant(s) from the header barrel (202) through a transfer line (302) into the reactor vessel (102). The plunger (402) is moved using a drive system (500). The header barrels (202) are optionally combined in a header block (200). The header block (200) is sealed to a plate (300) containing the transfer lines (302), which in turn is sealed to the reactor block (100). A latch mechanism (600) is provided for easy sealing of the reactor (100) and header blocks (200) to the plate (300). The entire apparatus (10) may be placed on a rocker or rotating plate for mixture as the reaction is proceeding.

Abstract:
Block copolymers are prepared by living-type or semi-living type free radical polymerization, with said copolymers having at least one random block comprised of at least one hydrophobic monomer and at least one hydrophilic monomer. The selection of hydrophobic and hydrophilic monomers in the random block is determined by the relative hydrophobicity of the monomers to impart selected solubility or dispersability in water and/or alcohols of the overall block copolymer.
