  • Process for the preparation of a rubber article having an outer polymer-coated surface and an inner chlorinated surface
    Patent number: 6764731
    Abstract: The present invention is related to a two-side treated formed rubber article having a polymer coating on the outer surface; and a chlorinated inner surface. It is also related to a process for making gloves using a polymer as a mold release and anti-blocking agent on the outside of the glove, and a chlorination of the glove inside surface. The rubber article can be formed as a powder-free glove.
    Type: Grant

  • Catalyzed water-soluble/dispersible reactive derivatives of polyimido compounds for modifying proteinaceous substrates
    Patent number: 6306378
    Abstract: This invention relates to a two-part system useful for treating proteinaceous substrates. The two-part system has a first part comprising a water-soluble/dispersible reactive polyimido compound and a second part comprising a nucleophilic catalytic agent. The polyimido compounds may be selected from the group consisting of polysuccinimide compounds, polyglutimide compounds, and copolymers of thereof. The polyimido compound may also comprise a functionalizing moiety that provides functionality to the polyimido compound and is preferably derived from a nucleophilic moiety selected from the group consisting of amines, alcohols, phenols, thiols, and carboxylates; and a water-solubilizing/dispersing moiety that provides water-solubility and/or water-dispersibility to the polyimido compound and is preferably derived from a nucleophilic moiety selected from the group consisting of amines, alcohols, phenols, thiols, and carboxylates.

  • Process for the polymerization tri-substituted silylalkynes
    Patent number: 4902763
    Abstract: Polymeric trisubstituted silylalkynes useful for forming gas separation membranes are prepared at accelerated polymerization rates and with improved yields in the presence of a Group VV or VIB Metal halide catalyst such as TaCl.sub.5, by employing about 0.1 to 5 mole %, based upon total alkyne concentration, of a trialkylgermylalkyne compound.
