A method for recovering catalytic metals from fluids containing catalytic metal colloids. Fluid compositions such as rinse solutions or dragout baths containing catalytic metal colloids are passed through a filter that entraps catalytic metal colloids on the filter. The catalytic metal colloids have a high affinity for the filter in contrast to other components of the fluids. The other components of the fluids pass through the filter while the catalytic colloids concentrate on the filter. The filter containing the catalytic metal colloids is burned, and the catalytic metal is retrieved. The method is economically efficient and environmentally friendly.

Abstract:
A method for recovering catalytic metals from compositions containing catalytic metal colloids. Compositions such as rinse solutions or dragout baths containing catalytic metal colloids are passed through a filter that entraps catalytic metal colloids from the solutions. The catalytic metal colloid has a high affinity for the filter in contrast to other components of the solutions. The other components of the solution pass through the filter concentrating the catalytic colloid on the filter. The filter containing the catalytic metal colloid is rinsed with an acid solution to remove the catalytic metal from the filter. The catalytic metal is collected in a suitable container or on an adsorbent such as a resin. The method is economically efficient and environmentally friendly.

Abstract:
A method for functionalizing a crosslinked polymer bead. The method comprises the steps of: (a) swelling the bead in a first solvent or solvent mixture to a volume from 200% to 310% of its volume when dry; and (b) contacting the bead with a functionalizing reagent in a second solvent or solvent mixture capable of swelling the bead to a volume from 200% to 310% of its volume when dry.

Abstract:
Olefin-based materials react with a range of catalysts and catalytic systems to form catalytic matrices, which are employed in the production of a variety of polyolefin products.
The present invention provides a method for producing a free flowing and/or non clumping resin that includes prior to drying, shrinking the resin under agitation. In one variant of the invention, the is a resin used in solid phase synthesis of peptides. In another aspect the invention provides a process of making a peptide using the free flowing resin described herein, and a polypeptide made using the process. Various therapeutics are then be made using the polypepdite.
Hydrozirconated Matrix And Process For Polyolefin Production
A hydrozirconated matrix for the production of polyolefins is disclosed. The hydrozirconated matrix is prepared from the reaction of an organozirconium composition and an olefin based material. A process is described for using the hydrozirconated matrix to prepare a range of polyolefin products.
