MOLDING POLYAMIDE COMPOSITION WHICH ARE STABLE TO ALCOHOLS AND BOILING WATER FROM ISOPHTHALIC ACID/DECAMETHYLENE DIAMINE/BIS (AMINO CYCLOHEXYL) METHANE

摘要

The invention relates to molding compositions which are stable with respect to alcohol and boiling water. The known molding compositions which are stable to boiling water and comprise amorphous copolyamides have unsatisfactory stability to alcohols. There is therefore a demand to improve molding compositions comprising polyamides in this respect. The invention provides molding compositions based on an amorphous copolyamide prepared from: (A) isophthalic acid; and (B) 20-80 mol % of n-decamethylene-1,10-diamine, and 20-80 mol % of bis(4-aminocyclohexyl)methane.
