An epoxidized diene star polymer having greater than 4 arms and comprising from 0.05 to 5 Meq of di-, tri- and tetra-substituted olefinic epoxides and the molecular weights of the arms are from 1,500 to 15,000.

James R Erickson, Scott Powers: Reverse two-hybrid method. ONYX Pharmaceuticals, Gregory Giotta, Tracy Dunn, June 11, 1996: US05525490 (49 worldwide citation)

The reverse two-hybrid method has been designed to provide a practical and efficient means of utilizing yeast cell-based assays to screen for molecules that can inhibit protein-protein interactions of interest. Existing two-hybrid systems involve reconstitution in yeast of a transcriptional activato ...

James R Erickson, Robert J Seidewand: Emulsion process for polymer particles. SCM Corporation, Thomas M Schmitz, October 7, 1980: US04226752 (44 worldwide citation)

An improved two-step process for producing large size emulsion polymer particles includes the steps of providing uniform size polymer particles in the first stage followed by a controlled second stage monomer polymerization which overcomes stability problems in large size composite emulsion polymer ...

Kirk J Abbey, James R Erickson: Epoxy modified emulsion polymers. SCM Corporation, Thomas M Schmitz, June 11, 1985: US04522962 (36 worldwide citation)

Emulsion polymers produced by polymerizing ethylenically unsaturated monomers in an aqueous medium can be substantially improved by incorporating into the monomer mixture a minor amount of blend of epoxy resin and glycidyl acrylate. The epoxy modified emulsion polymers are particularly useful as amb ...
