Claim:
A method of adhering or sealing at least one surface said method comprising (1) applying to at least one surface, a compound of formula (I) where R 1 is selected from a heteroatom or a substituted heteroatom which has electron withdrawing properties and R 6 is a bond or —C(O)—, —C(O)O—, —OC(O)—, C(S) or —S(O) 2 —; R 2 and R 3 are independently selected from (CR 8′ R 8 ) n , or a group CR 9 R 10 , —(CR 8′ R 8 CR 9 R 10 )— or —(CR 9 R 10 CR 8′ R 8 )— where n is 0, 1 or 2, R 8′ and R 8 are independently selected from hydrogen or alkyl, and either one of R 9 or R 10 is hydrogen and the other is an electron withdrawing group, or R 9 and R 10 together form an electron withdrawing group, R 4 and R 5 are independently selected from C, CH or CR 11 where R 11 is an electron withdrawing group, and R 7 is selected from hydrogen, an optionally substituted hydrocarbyl group, a perhaloalkyl group or a functional group; the dotted lines indicate the presence or absence of a bond, and X 1 is a group CX 2 X 3 where the dotted line bond to which it is attached is absent and a group CX 2 where the dotted line bond to which it is attached is present, Y 1 is a group CY 2 Y 3 where the dotted line bond to which it is attached is absent and a group CY 2 where the dotted line bond to which it is attached is present, and X 2 , X 3 , Y 2 and Y 3 are independently selected from hydrogen and fluorine; provided that i) at least one of (a) R 1 and R 6 or (b) R 2 and R 3 or (c) R 4 and R 5 includes an electron withdrawing group; ii) where R 2 and R 3 are both CH 2 , R 4 and R 5 are both CH, and R 1 is N, R 6 may not be selected from C(O) or —OC(O)—; and optionally a polymerisation initiator, and (2) allowing the compounds of formula (I) to polymerize in contact with said at least one surface to seal said surface and optionally a further surface such that the said at least one surface and said optional further surface are adhered or sealed together.
