Poly(thio)hydantoins are prepared by reacting an iso(thio)cyanate having at least two iso(thio)cyanate moieties with a compound of the formula <IMAGE> wherein R1 and R2 are the same or different and each represents hydrogen, halogen, a C1-C20 aliphatic group, a C7-C20 aliphatic-aromatic group, a C6-C20 aromatic group or a heterocyclic group having from 4 to 16 ring members and at least one N, O or S atom; A represents CN, COR, substituted or unsubstituted C1-C20 aliphatic group, C7-C20 aliphatic-aromatic group, C6-C20 aromatic group or a heterocyclic group having from 4 to 16 ring members and at least one N, O or S atom wherein the substituents are NO2, COOR4, CN, CO or OH; R and R4 are selected from the definition of R1 and R2 with the exclusion of halogen; M represents OH or <IMAGE> and R6 represents hydrogen, unsubstituted or substituted C2-C20 aliphatic, C5-C12 cycloaliphatic, C6-C20 aliphatic aromatic, or a C5-C12 aromatic or C5-C12 cycloaliphatic containing a heteroatom N, O or S in the ring, wherein the substituents are at least one halogen, C1-C10 alkyl, or C6-C12 aryl.
