Polymerised monomeric reactant

Further improvements in polymerised monomeric reactants were achieved by end capping the ethynyl terminated imide with resin precurser agents such as... 

The concept of norbornene-terminated oligoimides was further studied at the NASA Lewis Research Centre by researchers who developed the polymerisation of monomeric reactants (PMR) approach [38]. The method, represented in Fig. 18, involves a blend of both the dimethyl ester of 3,3 -benzophenonetetra-carboxylic acid 42 and the monomethylester of 5-norbornene-2,3-dicarboxylic acid 41 with 4,4 -methylenebisbenzeneamine 34 in solution in methanol.
