Plasticizer (polyethylene glycol 600) was added as 25% by volume of the viscous CA with agi-tation; this formed the final product which was dried in an oven at 60C until a constant weight in order to get the pro-duct ready for use. Before being shaped, the product was diluted with acetone to bring it into the form of a viscous fluid
which could be poured in a mold or on a smooth surface for shaping.
