| titleOfInvention | Method for the preparation of polymers that can be photochemically cross-linked |
| abstract | Polymers containing azidosulphonyl groups are prepared by reacting polymers containing active hydrogen atoms with a phenyl sulphazide compound containing at least one isocyanate group, or with a phenyl sulphochloride compound containing at least one isocyanate group and subsequently with sodium azide. Specified polymeric materials are gelatine, starch, cellulose, cellulose ethers and esters, polymers of vinyl alcohol which may contain units of comonomers such as olefins and conjugated di-olefins, vinyl esters, vinyl ethers, styrene, acrylic and methacrylic acids, esters and nitriles, vinyl and vinylidene chloride, and maleic anhydride, particularly partially saponified ethylene/vinyl acetate copolymers, and hydroxyl containing polyesters, polyethers, polyurethanes, polyamides and epoxy resins, e.g. condensates of alcohols, acids and amines with epihalohydrins. Specified isocyanates are m- and p-isocyanatobenzene sulphazides and sulphochlorides and 2-chloro-5-azidosulphonyl phenyl isocyanate. The reaction may be effected in solvents, e.g. formamide, dimethyl formamide, cyclohexanone, acetone, butyl acetate and pyridine, at room or higher temperatures. The products may be photo cross-linked, optionally in the presence of sensitizers, and may be spun or cast to form films, moulded into shaped articles, or coated on metals, paper, glass and plastics and selectively exposed to form resists. In examples saponified ethylene/vinyl acetate copolymers are reacted with (1) p- and (2) m-isocyanato benzene sulphazide; saponified vinyl acetate/vinyl chloride copolymers are reacted with (3) p- and (4) m-isocyanato benzene sulphochloride and sodium azide, and with (7) 2-chloro-5-azidosulphonyl phenyl isocyanate; (5) a 2,2-bis-(4-hydroxyphenyl) propane/epichlorohydrin condensate is reacted with p-isocyanato benzene sulphochloride and sodium azide; and (6) a partly hydrolysed cellulose acetate is reacted with p-isocyanato benzene sulphazide.ALSO:Isocyanato benzene sulphazides may be prepared by reacting the chlorosulphonyl acid chlorides with sodium azide and heating. In Example (1) p-chlorosulphonyl benzoyl chloride is reacted with sodium azide and heated to give p-isocyanato benzene sulphazide, and m-isocyanato benzene sulphazide and 2-chloro-5-azidosulphonyl phenyl isocyanate are prepared similarly. |
