MALEIC ACID DERIVATIVES, INTERMEDIATES FOR MALEIC ACID DERIVATIVES FOR PRODUCING THE SAME, AND PROCESSES FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/1999/018069

Kind Code:

A1

Abstract:

Maleic acid derivatives of general formula (1) (wherein one of R?1¿ and R?2¿ is alkyl or halogen-substituted alkyl, and the other is a polyethylene glycol residue, a polyethylene glycol monomethyl ether residue or a halogen-substituted alkyl; and R?3¿ and R?4¿ are each alkyleneimino; with the proviso that R?1¿ and R?2¿ are not the same). These derivatives are capable of forming self-assembly monomolecular films and also reversibly changing the wettability of the surfaces of the monomolecular films without detaching themselves from the substrate surfaces.
