Abstract
An improved method for injection molding of non-precatalyzed resins in which the catalyst and resin flows are injected in a mixing chamber co-current with one another angled toward the ejectment end of the mixing chamber, The resin flow is injected closer to the ejectment end of the mixing chamber than is the catalyst flow.
