Abstract
About 25% of all polymer products involve polymerization within the final mold. Processes including this stage are monomer casting, rubber molding, thermoset injection and compression molding. Most of these processes use thermosetting polymers, because thermosets must be crosslinked in their final shape and because linear polymers with sufficient molecular weight cannot react rapidly enough. Frequently, the cycle times are longer than those required for melt fabricating thermoplastics. Typically the thermosetting reactions are thermally activated, and thus require time for heat transfer to the material in addition to the time needed for the reaction. Recently, technology has been developed for rapid in situ polymerization to form articles directly from monomeric or oligomeric liquids. This process has come to be known as Reaction Injection Molding (RIM), and its modification as the reinforced RIM (RRIM) process.
