Реферат: According to the invention there is provided a method of treating textile fibres including the steps of: providing a polymeric precursor which includes a group of sub-formula (I) where R 2 and R 3 are independently selected from (CR 7 R 8 ) n , or a group CR 9 R 10 , CR 7 R 8 CR 9 R 10 or CR 9 R 10 CR 7 R 8 where n is 0, 1 or 2, R 7 and R 8 are independently selected from hydrogen, halo or hydrocarbyl, 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, and R 4 and R 5 are independently selected from CH or CR 11 where R 11 is an electron withdrawing group, the dotted lines indicate the presence or absence of a bond, 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, fluorine or other substituents, R 1 is selected from hydrogen, halo, nitro, hydrocarbyl, optionally substituted or interposed with functional groups, or −−R 3 −−R 5 ≡Y 1 , and R 13 is C(O) or S(0) 2 ; coating the textile fibres with the polymeric precursor; and polymerising the polymeric precursor so as to produce a polymeric coating on the textile fibres.
