WIPO Patent Application WO2000006533

B1

A compound of formula (I) where R<1> is CH and R<6> is a bond, or R<1> and R<6> together form an electron withdrawing group; 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 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, 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, 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; R<16> is a bridging group of valency r and r is an integer of 2 or more, subject to the following provisos: (i) that 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. These compounds are useful in the production of network polymers, for example for coatings or binders.
