Abstract:
A composition comprising monoaspartic acid esters and polyaspartic acid esters of formula (I),Xâ€”[NHâ€”CH(CH2â€”COOR2)â€”COOR1]mâ€ƒâ€ƒ(I) in which X represents an m-valent organic radical, optionally having one or more heteroatoms, obtained by removing the primary amino group or groups from a corresponding monoamine or polyamine in the molecular weight range from 60 to 6000 containing (cyclo)aliphatically or araliphatically bound primary amino groups, and which may contain further functional groups that are reactive with respect to isocyanate groups and/or are inert at temperatures up to 100Â° C., R1 and R2 represent identical or different organic radicals, and m represents an integer &gE;1, as well as an addition product prepared from a compound of formula (II) (component A), R1OOCâ€”CH&boxH;CHâ€”COOR2â€ƒâ€ƒ(II) and a thiol compound of formula (III) (component B), [HS]nâ€”R3â€ƒâ€ƒ(III) in which R3 represents an n-valent organic radical optionally having one or more heteroatoms, which optionally may also have other functional groups that are reactive or inert with respect to isocyanates, and n represents an integer &gE;1 and &lE;4.
