Abstract
A process comprising: a) reacting a diphenol monomer A with a monomer B having two locations for reaction with A to form arylene ether monomer C and b) reacting arylene ether monomer C with a diphenol monomer D to form a polymer, where monomer A isHX1-Q1-X1H; (II)monomer B isarylene ether monomer C isand monomer D iswherein: Q1 comprises at least one aryl or heteroaryl group; Q2 comprises at least one aryl or heteroaryl group; X1 is O bonded directly to an aryl carbon of Q1; X2 is O bonded directly to an aryl carbon of Q2; Z is a linker comprising at least one —(C(R2)2)— group; Y is a single bond or linker group (e.g., comprising up to about 50 carbons); R1 is independently at each occurrence H, a halogen, an alkyl group, a heteroalkyl group, an aryl group, or a heteroaryl group; R2 is independently at each occurrence H, an alkyl group, or a heteroalkyl group; and R3 is H or a crosslinkable group.
