Chemspeed’s MULTIPLANT/ AUTOPLANT POLY deck modularity allows the user to execute and perform a variety of single-site and multi-site catalyst synthesis workflows, incl. optimization / scale-up, in a fully or semi-automated fashion.
The heart of Chemspeed‘s solutions for emulsion, suspension, dispersion, solution, mass and pressure polymerization is to automate: reagents preparation, polymerization, work-up and analysis.
Example of emulsion polymerization:
- Step 1: water insoluble monomer is mixed in an aqueous solution containing a surfactant.
- Step 2: an initiator is added and the primary free radicals react with the monomer in aqueous phase to produce oligomeric radical species diffusing into monomer-swollen micelles.
- Step 3: the monomer diffuses from the aqueous phase into the micelles, this propagation phase induces the growth of the micelles.
- Step 4: the termination occurs when the monomer is no longer present or when the reaction is quenched.
