The compounds of formula (I) are described.n n n n n n n n In this formula,n n n L < 1 > is a main group atom,n n n L < 2 > is a neutral ligand,n n n M is a transition element or a metal element of group 13, 14, 15 or 16 of the periodic table,n n n x is the number of coordination sites of M,n n n R 1 is a polymerizable group,n n n R 2 , R 3 and R 4 are ligands,n n n R 5 is an anionic ligand.n n n The compounds or monomers of formula (I) can be converted into polymers by combining with one or more other known monomers such as methyl methacrylate. Thereafter, the polymers may be added as a binder to paint paints for preparing marine antifouling paint compositions. Also disclosed is a method for preventing surface contamination by applying a composition containing a metal complex compound of the general formula (I ') to a surface which is susceptible to contamination.n n n n n n n n Wherein M, x, L 2 , n and R 4 are the same as defined for general formula (I). |
