Abstract
Described herein are novel poly(aryl ether) polymers that contain naphthalene, terephenylene and/or anthracenylene units within their chains. Representative polymers are tough materials having excellent high temperature, oxidative and chemical resistance, and easy melt fabricability.
Claims2
Poly(aryl ethers) having repeating units of the formula
- --E--O--E'--O--
- wherein E is one or more:
- divalent aromatic radical selected from the group consisting of ##STR104## and E' is one or more divalent radical selected from the group consisting of:
- E, ##STR105## where A is the group ##STR106## p is an integer and is independently 1 or 2;
- m is independently 0 or 1 with the proviso that when m is 1 the linkage of the group A to the body of the E radical is via the carbonyl function of the A group, and n is an integer of 1 to 5;
- T and T.sub.1 can be the same or different and are independently hydrogen, C.sub.1 to C.sub.4 alkyl, C.sub.1 to C.sub.4 alkoxy, phenyl, .alpha.-styryl, .alpha.-methylstyryl or halogen;
- Q is independently a chemical bond, O, S, S--S, CH.sub.2 or CO, with the proviso that when E is a naphthylene containing group and both m's are zero and n is one, Q cannot be CO.
Poly(aryl ethers) having repeating units of the formula ##STR107## wherein T and T.sub.1 are independently hydrogen, C.sub.1 to C.sub.4 alkyl, C.sub.1 to C.sub.4 alkoxy, phenyl, .alpha.-styryl, .alpha.-methylstyryl or halogen and Q' is independently O or CO with the proviso that at least one Q' is an oxygen bridge.
