Abstract:
A method of adhering or sealing surfaces, said method comprising(1) applying to at least one surface, a compound of formula (I) â€ƒwhere; R2 and R3 are independently selected from (CR8â€²R8)n, or CR9R10, â€”(CR8â€²R8CR9R10)â€” or â€”(CR9R10CR8â€²R8)â€” where n is 0, 1 or 2, R8â€² and R8 are independently selected from hydrogen or alkyl, and either one of R9 or R10 is hydrogen and the other is an electron withdrawing group, or R9 and R10 together form an electron withdrawing group, R4 and R5 are independently selected from C, CH or CR11 where R11 is an electron withdrawing group, R6 is a bond or an electron withdrawing group; and R7 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 X1 is CX2X3 where the dotted line bond is absent and CX2 where the dotted line bond is present, Y1 is CY2Y3 where the dotted line bond is absent and CY2 where the dotted line bond is present, and X2, X3, Y2 and Y3 are independently selected from hydrogen or fluorine; provided that at least one of (a) R6 or (b) R2 and R3 or (c) R4 and R5 includes an electron withdrawing group; and optionally, a polymerisation initiator, and (2) allowing the compound of formula (I) to polymerise in contact with a second surface such that the said surfaces are adhered or sealed.
