Polymer Processing Institute

Reactive Extrusion Setup
The Polymer Processing Institute has had a long history of research in reactive processing.  Much of the contract research for industries is of the work conducted in one of three main categories:

  • Reactive Compatibilization
    • Create Stable Morphologies in Polymer Blends and Composites
    • Improve Mechanical and Thermal Properties
  • Monomer Grafting to a Polymer Backbone
    • Add Functionality/Polarity to Polymer Chains
    • Grafted Polymer to be used as a Compatibilizer for Polymer Blends/Composites
  • Polymerization Reactions
    • Addition as well as Condensation Types
    • Homo and Co polymerizations.  Up to Four Monomer Components have been Investigated
    • Typical Goal is to Perform Polymerizations in Continuous Processing Equipment.  Extrusion Equipment Primarily but not Exclusively Used

A systematic approach is used to determine the feasibility of a Reactive Polymer System.  The Process/Product Development project is custom designed on a case by case basis.  A typical approach is to investigate the system on a small-scale batch wise basis, then incorporate the information gained to pilot scale continuous equipment.  PPI has an extensive processing laboratory of pilot sized equipment which includes:

  • Batch mixers
  • Extruders; Single and Twin Screw, Co-and Counter-rotating, Intermeshing and Non-intermeshing
  • Continuous Stirred Tank Reactors;  to be used as Prereactors or for Complete Polymerizations
  • Liquid Metering Pumps; Capable of Pumping at High Pressures and Low Flow Rates
  • Jacketed Pumps, Lines, and Feed Ports to Control Component Temperature

Process laboratory is complemented by an extensive Polymer Characterization Laboratory.
