摘要:
A mixture of inherently conductive polymers and non-ionic waterborne polymers is disclosed. A preferred mixture is lignosulfonic acid-grafted polyaniline and a breathable polyurethane. Coatings of the mixture can be used as anti-fouling marine coatings; anti-static fabrics, coatings and packaging; batteries; conductive inks; conductive adhesives; EMI/RFI shielding articles, radar or microwave absorption articles, and sensors.
摘要:
A cathodic protection compound is disclosed. The coating includes sacrificial metallic particles less noble than metal in the metal substrate to be protected. The coating also includes inherently conductive polymer in an amount of less than 1 weight percent of total solids of the coating. A concentrate of the metallic particles and inherently conductive polymer can also be prepared.
摘要:
A mixture of inherently conductive polymer and plastisol is discolsed. Articles made from the mixture can be used as electrostatic dissipative (ESD) articles.
摘要:
A cathodic protection polymeric compound is disclosed. The compound has flowable material to serve as a binder, carbonaceous conductive media dispersed in the flowable material, sacrificial metal particles also dispersed in the flowable material. The carbonaceous conductive media serve as a carbon-based electron transfer agent and are in the form of particles, platelets, fibers, tubes, or combinations thereof. A galvanic circuit is formed by the metal particles serving as anodes, a metal substrate to be protected serving as the cathode, and the conductive media serving as the electron transfer agent. The flowable material can also include an ionically conductive or an inherently conductive polymer to further enhance the galvanic circuit.
摘要:
A mixture of poly(vinyl chloride) and epoxidized methyl soyate is disclosed. The epoxidized methyl soyate as a plasticizer replaces butyl benzyl phthalate which is conventionally used for the manufacture of multi-layer laminate sheet flooring or single layer tile flooring. The epoxidized methyl soyate, a bio-plasticizer, unexpectedly is a "drop-in" replacement for the butyl benzyl phthalate, both in terms of processing and performance. Also poly(vinyl chloride) - epoxidized methyl soyate mixtures have much better heat stability than poly(vinyl chloride) - butyl benzyl phthalate mixtures.
摘要:
A cathodic protection coating is disclosed that unexpectedlyt protects a treated metal substrate, notwithstanding the presence of a phosphate-containing conversion coating between the metal substrate and the cathodic protection compound. The cathodic protection coating includes sacrificial metallic particles less noble than metal in the metal substrate to be protected. The coating also includes inherently conductive polymer.
摘要:
Presently disclosed are high purity unsaturated fatty acid esters with an ester moiety characterized by having from five to seven members in a ring structure, which esters when epoxidized find particular utility as primary plasticizers in flexible polyvinyl halide applications. Also disclosed are processes for making the high purity esters.

摘要:
A soft, pelletizable poly(vinyl chloride) plastisol having a Shore A hardness of less than about 70 is disclosed. The plasticizers employed in the plastisol can be petroleum-based plasticizers or bioplasticizers or both. A method of gelation, fusion, and controlled cooling in an agitating chamber permits a conventional liquid plastisol to be transformed into the pelletizable plastisol strand. If a pelletizer is used after cooling into strands or other shapes, then pelletized plastisol results. The formulation of liquid plastisol for hardness is unaffected by the transformation. The solidified plastisol can be stored for later extrusion or molding into a final plastic article shape.
