Abstract
A new class of polymers include repeating units comprising one or more arylene units substituted with heterocyclic side groups. The heterocyclic substituted arylene repeat units have the general structural formula: ##STR1## wherein Het is a heterocyclic group, R is an optional substituent, x is 1 or 2, and y is less than or equal to 4-x.
Claims61
A polymer of the formula:
- ##STR26## wherein:
- up to three CH units in each aromatic ring may be replaced by nitrogen atoms;
- Het is a heterocyclic group;
- x is 1 or 2;
- y is less than or equal to 4-x;
- R is independently alkyl, aryl, alkoxy, aryloxy, ketone, aidehyde, amide, ester, sulfone, cyano, fluoro, and oligomeric or polymeric groups comprising polyalkeneoxy, polyaryleneoxy, polyarylenesulfate, polyarylene sulfone, polyphenoxyphenylketone, polystyrene, polyphenylene, polyamide and polyimide;
- Y is selected from the group consisting of nil, --Ar--, --Z--, --Z--Ar--, and --AR--Z--Ar--, where Z is a divalent group selected from the group consisting of --O--, --S--, --NR'--, --O(CO)--, --(CO)NH(CO)--, --NR'(CO)--, phthalimide, pyromellitimide, --CO--, --CH.sub.2 --, --CF.sub.2 -- and --CR'R"--, wherein R' and R" are independently alkyl or aryl, and taken together may be bridging, and where Ar is selected from the group consisting of arylene, heteroarylene and arylene and heteroarylene substituted with at least one R group;
- and
- n is greater than about 4.
