Appeal No. 93-4332
Application 07/707,717
APPENDIX
1. A process comprising:
(1) providing a monomer mixture comprising (a) a bisimide of
an unsaturated dicarboxylic acid, which bisimide can be
represented by the formula
in which Y is a substituted or unsubstituted divalent group
containing at least 2 carbon atoms and a carbon-carbon double
bond, and Z is a divalent linking group, and (b) a triene which
contains both a conjugated diene moiety capable of unhindered
Diels-Alder reaction with a Y group of the bisimide and a carbon-
carbon double bond separated from the conjugated pair by a
divalent linking group; and
(2) subjecting said monomer mixture to a non-gellilng
elevated temperature for a time sufficient to increase the
viscosity of the mixture and to enhance the solubility thereof in
an organic solvent.
2. The process of claim 1 in which the triene is
represented by one of formulas I and II
