Abstract:
An essentially dry, disposable biomedical electrode is disclosed having an improved electrically-conductive material at the interface between the electrode and the skin. The conductive material comprises a dermally-nonirritating cohesive, conformable, synthetic hydrophilic polymer containing at least 5 mole percent of monomer units containing a salt of a carboxylic acid.
Abstract:
A composition comprising a radiation-curable polymer, said polymer being crosslinkable and having pendant ethylenically unsaturated peptide groups is disclosed. Such polymers are useful in the field of graphic arts.
Abstract:
High performance thermoplastic pressure sensitive adhesives are prepared by the copolymerization of N-(meth)-acryloylamino acids and acid derivatives with long-chained alkyl acrylates. The copolymers can be formulated into tapes that possess an excellent threefold balance of the necessary tape properties of tack, adhesion and cohesion.
Abstract:
Hydrophilic compositions are described, which are prepared from a first component oligomer containing pendent hydrophilic groups and pendent reactive functional groups capable of reaction at effective rates (at normal processing temperatures), with a co-reactive second component possessing functionality that is complementary to that of the first oligomer. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices.
Abstract:
The present invention provides crosslinkable compositions useful in the preparation of hydrophilic gels, and are prepared from oligomers having pendent hydrophilic, poly(alkylene oxide) groups, pendent photoinitiator groups, and optionally polymerizable functional groups, and crosslinked by polyfunctional poly(alkylene oxides).
Abstract:
Photoiniferters for controlled radical polymerizations are described. The photoiniferters have an azlactone or ring-opened azlactone moiety to provide telechelic (co)polymers.

Abstract:
A process for preparing a polarizer is described whereby an article comprising an oriented, vinylalcohol polymer film layer, and an acid donor layer comprising a photoacid generator, is exposed to radiant energy at a temperature sufficient to effect a partial dehydration of the vinylalcohol polymer to a vinylalcohol/poly(acetylene) copolymer.
Abstract:
A pavement marking composition comprises a sulfopoly(ester-urethane) polymer which comprises in its backbone at least one non-terminal arylene or alkylene group comprising a pendant sulfonic acid group or salt thereof, the polymer of said pavement marking composition being terminated by at least one hydrolyzable silyl group. A method of making the composition is disclosed. The pavement marking composition can further comprise at least one of pigments, optical elements, fillers, or other adjuvants. Particularly desirable adjuvants include optical elements, particularly retroreflective elements, skid-resistant particles, and pigments.
