ABSTRACT: Reaction Injection Moulding (RIM) is a reactive process for polymer processing where two, or
more, monomers, having low viscosity, impinge at high speed in a cylindrical mixing chamber. The performance
of the RIM process is highly dependent on the contacting of the two opposed monomer jet streams, i.e. of the
mixing of the two monomers. ...
