Flexible poly(amino ethers) for barrier packaging

A thermoplastic hydroxyfunctional polyaminoether represented by the formula:

• ##STR12## wherein each A is individually an amino group represented by one of the formulas:
• ##STR13## wherein R.sub.1 is hydrogen, methyl, or mixtures thereof;
• R.sub.2 is C.sub.2 -C.sub.20 alkylene or phenylene;
• R.sub.3 is C.sub.2 -C.sub.10 substituted or unsubstituted alkylene wherein the substituent(s) is alkylamido, hydroxy, alkoxy, halo, cyano, aryloxy, alkylcarbonyl or arylcarbonyl;
• R.sub.4 is substituted or unsubstituted C.sub.2 -C.sub.20 alkylene wherein the substituent(s) is the same as that for R.sub.3 and Y is individually alkylamido, hydroxy, alkoxy, halo, cyano, aryloxy, alkylcarbonyl or arylcarbonyl;
• B is represented by the formula:
• ##STR14## wherein R.sub.1 is hydrogen, methyl or mixtures thereof;
• and R.sub.5 is a C.sub.1 -C.sub.10 alkyl;
• y is from 1 to about 40;
• each Z is individually an alkylene, a poly(alkylene oxide), substituted or unsubstituted m-phenylene, p-phenylene, carbonyldiphenylene, sulfonyldiphenylene, isopropylidenediphenylene, methylenediphenylene, biphenylene, oxidiphenylene, diphenylene sulfide, naphthylene, diphenylenecyano-methane, or mixtures thereof;
• wherein the substituent(s) is alkylamido, hydroxy, alkoxy, halo, cyano, aryloxy, alkylcarbonyl or arylcarbonyl or mixtures thereof;
• w is a whole number from about 10 to about 400;
• and x is from 0.2 to 0.8.
