Abstract:
Pressure-sensitive adhesive tape having a photopolymerized acrylate polymer adhesive which has been crosslinked by a polyacrylic-functional crosslinking monomer such as trimethyol-propane triacrylate.
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 consists essentially of a cohesive, conformable, nonionic hydrophilic synthetic polymer.
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:
Normally tacky and pressure-sensitive adhesive tapes, labels, etc. which, when adhered to dry fibrous webs, remain firmly attached when the web and adhesive are thereafter exposed to moist conditions. These performance characteristics, which are not found when conventional pressure-sensitive adhesives are used, result from employing acrylate-based copolymer adhesives made from specific monomers and having inherent viscosities related to the monomers employed.
Abstract:
The present invention concerns a process for producing synthetic coal and aqueous liquid plant fertilizing solution products from a fermentation residue such as is left over from the corn based process of producing ethanol. The synthetic coal has a high heat value commensurate with naturally occurring coals and is lower in ash and sulfur content and thus has value as a clean burning energy source. The aqueous fertilizer includes commercially useful amounts of phosphorous, potassium and nitrogen in solution. The process of the invention is also energy efficient in that the products produced thereby involve the use of substantially less energy as compared to the traditional methods of processing fermentation residues in the corn based ethanol production industry.
Abstract:
Hydrophilic compositions are described, which are prepared from a first oligomer containing pendent polymerizable groups and pendent hydrophilic groups, crosslinked with a co-reactive second component oligomer possessing photoinitiator groups. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices.
Abstract:
The present invention provides cross linkable compositions useful in the preparation of hydrophilic gels, and are prepared from obligers having pendent hydrophilic ploy(alkenylene oxide) groups, and pendent pulverizable functional groups, and cross linked by polyfunctional ploy(alkenylene oxides).
Abstract:
Initiators for atom transfer radical polymerizations are described. The initiators have an azlactone or ring-opened azlactone moiety to provide telechelic (co)polymers.
Abstract:
The present invention provides melt-processible adhesive compositions prepared from a first oligomer containing reactive functional groups capable of reaction at effective rates (at normal processing temperatures) with a co-reactive second component oligomer possessing functionality that is complementary to that of the first oligomer. The compositions may be used as coatings, including hard surface coatings, clear coatings, powder coatings and pattern coatings; as adhesives, including pressure sensitive adhesives and hot melt adhesives; as sealants; as optical coatings; as blown microfibers (BMF); as high refractive index optical materials; as barrier films; in microreplication; as low adhesion backsizes, (LABs) and as release coatings.
Abstract:
Chain transfer agents for controlled radical polymerizations (RAFT) are described. The chain transfer agents have an azlactone or ring-opened azlactone moiety to provide telechelic (co)polymers.
