Abstract

Abstract A substrate surface is lubricated or passivated by applying thereto a monomolecular layer of a compound having the formula ##STR1## wherein n is 6 to 20, each of m and L is 6 to 10, X is --CH═CH--or --C.tbd.C--, and M is a divalent cation, and polymerizing said layer in situ.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 59 words
A process for lubricating or passivating a solid substrate surface comprising applying thereto a monomolecular layer of material having the formula ##STR6## wherein n is 6 to 20, each of m and L is 6 to 10, X is --CH.tbd.CH-- or --C.tbd.C--, and M is a divalent cation, and polymerizing said layer in situ by exposing it to radiation.
Claim 2
Dependent Claim 59 words
A process for lubricating or passivating a solid substrate surface comprising applying thereto a monomolecular layer of material having the formula ##STR6## wherein n is 6 to 20, each of m and L is 6 to 10, X is --CH.tbd.CH-- or --C.tbd.C--, and M is a divalent cation, and polymerizing said layer in situ by exposing it to radiation.
Claim 3
Dependent Claim 25 words
A process as claimed in claim 1 wherein the polymerization is carried out by exposing the monomolecular layer to ultra violet or gamma ray radiation.
Claim 4
Dependent Claim 15 words
A process as claimed in claim 1 wherein the solid substrate is a hydrophilic surface.
Claim 5
Dependent Claim 14 words
A process as claimed in claim 1 wherein the substrate is a metal oxide.
Claim 6
Dependent Claim 13 words
A process as claimed in claim 1 wherein the substrate is silicon dioxide.
