Method of producing a polymeric material, polymer, monomeric compound and method of preparing a monomeric compound

Abstract

A method of producing a polymeric material, said method including the step of subjecting a starting material which includes a group of sub-formula (XIII) where R16 is selected from hydrogen, halo, nitro, hydrocarbyl, optionally substituted or interposed with functional groups, or R2 and R3 are independently selected from (CR6R7)n or a group CR8R9, CR6R7CR8R9 or CR8R9CR6R7 where n is 0, 1 or 2, R6 and R7 are independently selected from hydrogen or alkyl, and either one of R8 or R9 is hydrogen and the other is an electron withdrawing group, or R8 or R9 together form an electron withdrawing group; and R4 and R5 are independently selected from CH or CR1o where CR1o is an electron withdrawing group, the dotted lines indicate the presence or absence of a bond, X1 is a group CX2X3 where the dotted line bond to which it is attached is absent and a group CX2 where the dotted line bond to which it is attached is present, Y1 is a group CY2Y3 where the dotted line bond to which it is attached is absent and a group CY2 where the dotted line bond to which it is attached is present, and X2 and X3, and, if present, Y2 and Y3, are each a C1 to C4 alkyl group; to conditions under which polymerisation of the starting material occurs.
