Abstract:
A method of coating a surface with a polymer layer, which method comprises exposing said surface to a pulsed plasma comprising a compound of formula (I) where R1, R2 and R3 are independently selected from hydrogen, alkyl, haloalkyl or aryl optionally substituted by halo, provided that at least one of R1, R2 and R3 is hydrogen, and R4 is a group Xâ€”R5, where R5 is an alkyl or haloalkyl group, and X is: a bond; or a group of formula â€”C(O)O(CH2)nYâ€” where n is an integer of from 1 to 10 and Y is a bond or a sulphonamide group; or a group â€”(O)pR6(O)q(CH2)tâ€” where R6 is aryl optionally substituted by halo, p is 0 or 1, q is 0 or 1 and t is 0 or an integer of from 1 to 10, provided that where q is 1, t is other than 0; so as to form an oil and/or water repellent coating on said surface.
