Method for the preparation of aminoalkyl fumarates
Abstract
Abstract AMINOALKYL FUMARATES HAVING THE FOLLOWING FORMULA: B-(CH2)N-CH(-A)-OOC-CH=CH-COO-CH(-A)-(CH2)N-B WHEREIN: B IS SELECTED FROM THE GROUP CONSISTING OF TERTIARY ALIPHATIC AMINO GROUPS CONTAINING FROM 2 TO 12 CARBON ATOMS AND PIPERIDINO; A IS H, CH3 OR CH2-B, AND N IS AN INTEGER OF 1 TO 2, ARE PRODUCED BY REACTING MALEIC ANHYDRINE AND AMINO ALCOHOLS HAVING THE GENERAL FORMULA HO-CH(-A)-(CH2)N-B AT REFLUX TEMPERATURE IN THE PRESENCE OF AN ESTERIFICATION CATALYST AND AND INERT SOLVENT WHILE BUBBLING NITROGEN THROUGH THE REACTION MIXTURE AND CONTINUOUSLY DISTILLING OFF THE WATER FORMED IN THE COURSE OF THE REACTION IN THE FORM OF AN AZEOTROPE WITH THE SOLVENT. THE AMINOALKYL FUMARATES MAY BE COPOLYMERIZED WITH OTHER VINYL TYPE MONOMERS TO INCORPORATE POLAR AMINO GROUPS INTO POLYMER MOLECULES TO IMPROVE THE CHARACTERISTICS OF COLORABILITY, ADHESION TO VARIOUS MATERIALS, RESISTANCE TO TEMPERATURE SHOCKS AND ANTISTATIC PROPERTIES.
