3. Polymer processing

The three monomers are prepared and delivered in solution in approximately 50% solvent (mainly methanol). This concentration is necessary for fiber pre-impregnation (cf. preparation of composites § 5.1 ).

The materials are produced by transforming the solution into a three-dimensional polymer, without isolating the intermediate thermosetting oligomer (resin) stage. The evolution of the product's viscosity from the base solution is...
