Polymers

PHMO

Boron Molecular can provide polyhexamethylene oxide (PHMO), a 1,6-hexanediol based polyether with a molecular weight in the 650-750 range.  PHMO is used as a raw material in the manufacture of biomedical polyurethanes (Elast-EonTM).

 

PDMS

Boron Molecular can supply polydimethylsiloxanes (PDMS),a silicone based polymer.  PDMS has applications as a surfactant, anti-foaming agent, hydraulic fluid and in lithography, medicines and cosmetics. PDMS can be reacted with polyhexamethylene oxide (PHMO) to produce a polyurethane elastomer, which has biomedical applications (Elast-EonTM)

 

POLYANILINES

Solution processable polyanilines

Polyaniline (PANI) is a semi-flexible, rod-type, conducting polymer with high intrinsic electrical conductivity. PANI is unique among conducting polymers in that its conductivity can be reversibly controlled either electrochemically or chemically.  Commercial applications of polyaniline include, electrostatic dissipation, anticorrosion coatings, rechargeable batteries, various electronic devices, sensor, organic photovoltaics, and separation membranes. The widespread use of PANI, however, has been severely hampered by its limited organic solution processability.

Boron Molecular can now provide xylene soluble solutions of doped PANI emeraldine salts in commercial quantities.
