Abstract

Some design strategies for structural reaction injection molding (S‐RIM) and resin transfer molding (RTM) are presented. Our approach makes use of moldability diagrams to define the parameters necessary to meet the process requirements. Moldability diagrams are presented for the filling and curing steps. The criterion for selecting the amount of fiber reinforcement, injection time, catalyst level, and process temperatures in order to optimize properties and demold time is described.

Syndiotactic polystyrene (sPS) has successfully been produced using a novel reaction injection molding (RIM) process and a metallocene catalyst. Previous studies have shown that many of the requirements for a RIM process are achievable. However, problems due to incomplete conversion of monomer have
