摘要 |
The present invention relates to production processes for reactive monomer species. The method described herein may be used in a variety of reactive monomer production processes to optimise the use of polymerisation inhibitor compounds, which may lead to further advantages such as debottlenecking or elimination of process plant separation unit(s). The method provides for the separation of oligomeric/polymeric species, inhibitor compounds and reactive monomer, optionally in the presence of unreacted raw materials or solvent(s), within the production process by means of membrane filtration, particularly through the use of solvent stable membranes, and in particular by applying organic solvent nanofiltration membranes. |
