Appeal 2007-0650
Application 10/808,264
I. BACKGROUND
The invention relates to a polyaromatic ether, a process of
preparing the polyaromatic ether, and a process of preparing an
oligomer based on the polyaromatic ether. Claims 1, 22, and 26 are
illustrative of the subject matter on appeal:
1. A polyaromatic ether comprising the formula:
–(–O–Ar–)n– ;
wherein Ar is an independently selected divalent aromatic
radical with or without substituents containing one or
more fused aromatic rings, one more non-fused aromatic
rings without intervening functional groups, or
combinations thereof wherein the radical sites are on the
same or different aromatic rings; and
wherein n is an integer greater than or equal to 7.
22. A process of preparing a polyaromatic ether comprising the
formula:
–(–O–Ar–)n– ;
wherein Ar is an independently selected divalent aromatic
radical with or without substituents containing one or
more fused aromatic rings, one or more non-fused
aromatic rings without intervening functional groups, or
combinations thereof wherein the radical sites are on the
same or different aromatic rings;
comprising the step of reacting a dihydroxyaromatic with a
dihaloaromatic;
wherein neither the dihydroxyaromatic nor the
dihaloaromatic is present in an excess amount; and
wherein the reaction is performed in the presence of a
