Polyamide-like condensation products and process for preparing the same

Claim 1

A PROCESS FOR THE PREPARATION OF POLYAMIDE-LIKE CONDENSATION PRODUCTS WHICH COMPRISES REACTING (1) AT LEAST ONE MEMBER OF A GROUP CONSISTING OF EPOXIDIZED FAT ACIDS AND ESTERS OF EPOXIDIZED FAT ACIDS OF SATURATED MONOHYDRIC ALIPHATIC ALCOHOLS HAVING A BOILING POINT NOT ABOVE ABOUT 200*C. AND (2) AT LEAST ONE MEMBER OF A GROUP CONSISTING OF HYDROCARBON DICARBOXYLIC ACIDS HAVING NOT MORE THAN 10 CARBON ATOMS IN A MOL RATIO OF 0.5 TO 1.0 MOL OF DICARBOXYLIC ACID PER MOL OF OXIRANE GROUPS IN SAID EXPXIDIZED FA ACIDS AND ESTERS UNDER ELEVATED TEMPERATURE CONDITIONS OF ABOUT 200*C. UNTIL AN ACID NUMBER OF NOT MORE THAN 30 IS OBTAINED ABOVE THAT THERETICALLY OBTAINABLE, COOLING THE REACTION PRODUCT TO BETWEEN ABOUT 70* AND ABOUT 80*C., ADDING A POLYAMINE HAVING THE FORMULA R-NH-CH2-CH2-NH2 WHEREIN R IS A MEMBER OF THE GROUP CONSISTING OF H AND -(CH2-CH2-NH2), HEATING THE RESULTANT MIXTURE AT TEMPERATURE OF ABOUT 200*C. AND TERMINATING THE REACTION WHILE THE SAID CONDENSATION PRODUCT IS STILL FUSIBLE.
