Appeal No. 1998-1625
Application 08/306,517
THE INVENTION
The appellants claim a method of manufacturing a
chemically adsorbed film. Claim 13 is illustrative:
13. A method of manufacturing a chemically adsorbed
film, which film comprises graft molecules and stem molecules,
said method comprising:
(a) providing a substrate surface, wherein said surface
comprises active hydrogen atoms or an alkali metal,
(b) contacting said substrate surface with first
chemical admolecules, said first admolecules containing at
least one functional group shown in formula [A] or formula [B]
and,
wherein said admolecules promote a dehydrochlorination or
alcohol elimination reaction, so as to provide stem molecules
covalently bonded to the substrate surface;
(c) removing unreached first chemical admolecules,
(d) reacting the substrate surface with water so as to
substitute one or more members of the group consisting of a
halogen group and an alkoxyl group with a hydroxyl group,
(e) contacting said substrate surface with second
chemical admolecules containing at least one functional group
selected from the group consisting of formulas [C], [D], [E],
[F], and [G], and wherein said second admolecules promote one
of a dehydrochlorination, water elimination or alcohol
elimination reaction, removing unreached second chemical
admolecules and reacting the substrate surface with water so
as to provide graft molecules bonded to said stem molecules;
wherein,
Formula [A] is -AXm,
-2-2
