<p>1533578 Electron-conducting polymer compositions MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 13 Oct 1975 [14 Oct 1974 19 Nov 1974] 41783/75 Headings C3V and C3R [Also in Division H1] Electron-conductive paints for use in secondary-electron multipliers are exemplified by compositions containing either electronconducting inorganic additives or polymer systems which contain or are treated with a compound which forms change transfer complexes. Exemplified additives are: silver powder, furnace black, acetylene black and channel black, which are used in an ethylenevinyl acetate copolymer, polyvinyl chloride, an epoxy resin, or a polyimide varnish consisting of 15% polypyrromelimide. Exemplified polymer/complexing agent systems are tetracyanoquinodimethane + 2 - vinyl pyridine/ vinyl acetate copolymer; 2-vinyl pyridine/ ethylene copolymer aftertreated with tetracyanoethylene after treated with tetracyanoquinodimethane; polyurethane foam aftertreated with triethylammonium (TCNQ) 2 ; polyvinyl chloride+ +p-chloranil; and polystyrene +N,N,N<SP>1</SP>,N<SP>1</SP>- tetramethyl - p - phenylenediamine, and aftertreated with tetracyanoquinodimethane.</p> |
