hydrolysis/dehydrohalogenation/Heck coupling was used to synthesize styrene sulfonate salts from iodoarenes and chloroethanesulfonyl chloride in good to excellent yields. Methodology was applicable for heterocyclic as well as disubstituted iodoarenes. Some of the key features of this synthetic methodology include the use of phosphine free catalytic system, water as an environmentally friendly solvent
Novel styrene sulfonate-based polymers and cation exchange membranes which are particularly suitable for use in electrodialysis of whey and improved methods for electrodialysis of whey are disclosed.

Particles capable of being bound by viruses, having a particle diameter of 0.05 &mgr;m to 300 &mgr;m and having either a cationic group or an anionic group or both at their surfaces. Also disclosed are a method of separating or detecting viruses and a virus-separating reagent, which make use of such particles. The particles enable simultaneous and simple treatment of a large number of specimens by a simple means.

To protect photographic films from imaging by static discharges during manufacturing and customer use, copolymers of sulfonated monomers and primary amine monomers are coated on a film base and crosslinked with an aldehyde such as glutaraldehyde, giving a water-resistant, permanent, conductive (i.e., antistatic) layer.
This invention relates to hot melt adhesive compositions which includes a polymer complex of an amine containing polymer and a co- or terpolymer, about 3 to about 100 parts by weight of a polymer complex per 100 parts by weight of the highly unsaturated hydrocarbon rubber, wherein the neutralized sulfonated elastomeric polymer has about 0.2 to about 5 weight percent of chemically combined sulfur and about 25 to about 200 parts by weight of a hydrocarbon resin of a petroleum or coal tar distillate, aliphatic dienes and mono and diolefins, cyclic olefins of 5 to 6 carbon atoms and hydrogenated poly cyclics per 100 parts by weight of the polymer complex.
