Poly(aryl ether)s containing the diphenylethylene moiety, synthesized
from 1,1-bis(4-fluorophenyl)ethylene or 1,1-bis(4-hydroxyphenyl)ethyle
ne, are thermally crosslinkable. Characterization and crosslinking stu
dies of these polymers were carried out by GPC, DSC, TGA, and NMR. The
solvent resistance and T-g's of the resulting crosslinked networks in
crease after crosslinking. Thermogravimetric analysis shows that no si
gnificant mass loss accompanies the crosslinking reaction. (C) 1995 Jo
