Technology

Boron Molecular is able to offer custom manufacture of polymers to your specific requirements using RAFT polymerization, and anionic polymerisation.  Boron Molecular’s ability to supply RAFT Agents (chain transfer agents for free radical polymerisation) at commercial scale provides a seamless progression from monomers to polymers at any scale. We have the analytical capability to analyze small molecular weight monomers by 1H NMR and GC and polymers by size exclusion chromatography (GPC).

RAFT Polymerization

RAFT (Reversible Addition Fragmentation chain Transfer) polymerization technology represents a versatile controlled radical polymerisation (CRP) technique for making polymers.

This technology has revolutionized polymer synthesis and spawned a new generation of polymeric materials, with many new applications in a wide range of fields including engineering materials, electronics, healthcare and biotechnology expected.

Using RAFT polymerization technology (RAFT) the production of well-defined, end-functionalized polymers, with precisely controlled structure, molecular weight, polydispersity, and with varied functionality can be easily achieved. RAFT is tolerant to a wide variety of reaction conditions and functionalities, and can be performed on existing conventional free-radical polymerization equipment.

Anionic Polymerization

Anionic polymerization is a type of “living” chain-growth addition polymerisation technique in which the active propagating centres are anions, involving the reaction of anionic initiators, typically alkyl lithiums, and vinyl monomers. Like RAFT technology, anionic polymerisation allows for the control of structure and composition of the product polymer.

A practical limitation anionic polymerization involves the very strict experimental requirements to ensure survival of the propagation anionic species. To this end,

Boron Molecular is working closely with CSIRO to develop the use of flow chemistry in the manufacture of polymers by anionic polymerization techniques to help overcome the difficulties with maintaining of stringent reactions conditions to ensure optimal and reproducible outcomes..
