ABSTRACT:
A method of moulding a shaped article from a curable composition in which the composition is cured in a mould comprising at least two mould parts defining a cavity characterized in that prior to introducing the curable composition into the mould cavity, the pressure inside the cavity is increased above atmospheric pressure, preferably to at least 0.3 bar above atmospheric pressure, the dispersion is injected into the mould against this pressure and is subsequently cured. The method is useful for overcoming problems of color banding on the surface of the moulding which originate in the filling process and are particularly evident when high mould temperatures are used.
