Thermally stable polyetheramines

A laminate structure comprising one or more layers of an organic polymer and one or more layers of a hydroxy-functionalized polyetheramine, wherein said hydroxy-functionalized polyetheramine layer is adhered directly to a contiguous organic polymer layer without an adhesive layer therebetween, the hydroxy-functionalized polyetheramine having the formula:

• ##STR7## wherein each A is independently an amine moiety and each B is independently a divalent aromatic moiety;
• R.sup.1 is hydrogen or a hydrocarbyl moiety;
• each X is independently hydrogen, a primary amino moiety, a hydroxyl moiety, an alkyl, heteroalkyl, inertly substituted alkyl or inertly substituted heteroalkyl group, an aryl or inertly substituted aryl group;
• an alkoxy or inertly substituted alkoxy group;
• an aryloxy or inertly substituted aryloxy group;
• an alkanethio or inertly substituted alkanethio group:
• an arenethio or inertly substituted arenethio group;
• wherein the substituent(s) is hydroxyl, cyano, halo, arlyloxy, alkylamido, arylamido, alkylcarbonyl, or arylcarbonyl;
• or independently represented by any one of the formulas:
• ##STR8## wherein R.sup.5 is independently an alkyl or heteroalkyl, inertly substituted alkyl or heteroalkyl, aryl or inertly substituted aryl group, wherein the substituent(s) is cyano, halo, arlyloxy, alkylamido, arylamido, alkylcarbonyl, or arylcarbonyl:
• R.sup.6 is independently hydrogen, an alkyl or heteroalkyl, inertly substituted alkyl or heteroalkyl, aryl or inertly substituted aryl group, wherein the substituent(s) is the same as that for R.sup.5 ;
• and R.sup.7 is an alkylene or heteroalkylene, inertly substituted alkylene or heteroalkylene, arylene or inertly substituted arylene moiety, wherein the substituent(s)is alkylamido, hydroxy, alkoxy, halo, cyano, aryloxy, alkylcarbonyl or arylcarbonyl;
• or a combination thereof with a monovalent moiety which is a secondary or tertiary amine, and n is a whole number from about 5 to about 1000.
