ABSTRACT:
A method of making molding compounds, and particularly sheet molding compounds, wherein the reactive monomers are mixed directly with high density inorganic fillers and other ingredients of a molding compound. The monomers are converted to a resin insitu that is in or approaching the B-stage, so that the material is handleable as a solid and is moldable. Because of the amount, type, and thermal conductivity of the fillers, the resinification can be done quickly in a continuous process, by reason of the fact that the monomers are spread over a large surface area of inert fillers to provide good heat transfer, and exceedingly good process control.
