Abstract
PURPOSE: To prepare polyimine molded articles useful as films, fibers,cast moldings, adhesives and laminates, having excellent hydrolytic, chemical, and heat resistance, by molding the polyimine in the presence of a phenol and reducing the amount of the residual phenol.
CONSTITUTION: A dialdehyde I (Ar1 is 4W40C aromatic group) is reacted with a diamine II (Ar2 is 4W40C aromatic group) or an aminoaldehyde III (Ar3 is 4-40C aromatic group) at 0W120°C to give a polymer, wherein the example of the above aromatic group is expressed by the formula IV. The polymer V or VI is dissolved in a phenolic compound, e.g. cresol, etc., and cast or melt molded. Subsequently the amount of the residual phenolic compound is controlled to <3.5 wt.% at ≥ at a temperature 40°C higher than the boiling point of the phenolic compound, and also below the thermal decomposition temperature for the polymer, to provide the desired molded articles
