Initiator/Stabilizer FAQs

An article regarding common FAQs for initiators and stabilizers.

Reversible Addition Fragmentation Chain Transfer (RAFT) Polymerization

RAFT (Reversible Addition Fragmentation chain Transfer) polymerization is a reversible deactivation radical polymerization (RDRP) and one of the more versatile methods for providing living characteristics to radical polymerization.

Continuous Flow Manufacturing for Monomer Synthesis

The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear contact lenses have the potential to fill this need for many customers; however, their widespread use is constrained by higher costs compared to weekly- or monthly-based lenses. New approaches that improve cost structure and result in higher quality raw materials are needed to help make contact lenses more affordable and accelerate growth of the contact lens market.

Preparation of High Refractive Index Films on PET Substrates

Zirconium bromonorbornanelactone carboxylate triacrylate (PRM30) is a zirconium-containing multifunctional acrylate useful for producing cured, transparent films with high refractive indices.

RAFT Polymerization Procedures

RAFT (Reversible Addition-Fragmentation chain Transfer) is a form of living radical polymerization involving conventional free radical polymerization of a substituted monomer in the presence of a suitable chain transfer (RAFT) reagent.

Concepts and Tools for RAFT Polymerization

We present an article about RAFT, or Reversible Addition/Fragmentation Chain Transfer, which is a form of living radical polymerization.
