Abstract

From fundamental and technological points of view RIM is a complex process.1 Fast reactions are required to form, in many applications, network materials and the reactions must by synchronised with the process so that the mould is filled with liquid reacting material, the material becoming solid at complete filling. The rates of reaction occurring between the two liquid reactant feeds which are mixed prior to mould filling must be well controlled, as must be the molecular growth process leading to the final, solid material. The important point in the polymerization is the gel point, which in terms of reactant flow defines the point of infinite viscosity.2,3
