BM1640 Technical Note

BM1640

2-(Butylthiocarbonothioylthio)propanoic acid

CAS RN: 480436-46-2

MF: C₈H₁₄O₂S₃

MW: 238.39

Product Description

BM1640 is a trithiocarbonate chain transfer agent (CTA), also referred to as a RAFT Agent, that can control chain growth in free radical polymerization, producing polymers with well-defined molecular weights, and low polydispersities. 

BM1640 can be used to control homo- and co-polymerization of acrylic acid, acrylates, acrylamides, and styrenes. It is soluble in organic media.

BM1640 is a stable solid that can be provided from gram to metric tonne quantities.

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.  This material has a broad range of applications in the development of materials that are able to
dissipate electrostatic potentials and also in the development of electrically conductive materials, coatings and composites.  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, toluene, NMP, CHCl3, Chloroacetic acid soluble solutions of doped PANI emeraldine salts in commercial quantities.
