Abstract
This invention discloses a process for making polymerizable and/or reactable vinyl monomer oligomers with narrow molecular weight distributions using catalytic distillation and a catalyst situated in an immobile catalyst bed in a reaction zone of the distillation column reactor. The polymerizable oligomer products comprise at least 50% by weight of a single molecular weight oligomer fraction.
