RAFT gives access to polymers of predetermined molecular size with very narrow molecular size distribution. It also allows the controlled synthesis of complex structures such as diblock, multiblock, hyperbranched and star shaped polymers, polymeric microgels and nanospheres. RAFT is tolerant to a wide variety of reaction conditions and functionalities and can be performed on existing conventional free-radical polymerization equipment.
Controlled size and narrow size distribution are important because they desirably impact many properties, such as viscosity and processability, while structures such as multiblock and star shaped polymers have unique properties that are sought after for many applications.
Boron Molecular specialises in the synthesis of precision engineered polymers for customers on an exclusive basis. We also provide extensive technical support for customers who are trialling our RAFT Agents..
Boron Molecular specialises in the synthesis of polyanilines (PANI), which is a well-studied electroactive polymer with high intrinsic electrical conductivity. PANI is unique among conducting polymers as its conductivity can be reversibly controlled. Nevertheless, most available PANI has poor-solubility in common solvents limiting its application.
Boron Molecular now provides toluene soluble solutions of highly defined and high quality doped PANI in commercial quantities.
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. BM1720, CAS Number 178274-40-30, (Polyaniline-dinonylnaphthalenesulphonic acid, 50% solution in toluene is available in our catalogue. For the detailed information of PANI, click here.
While Boron Molecular specializes in the synthesis of advanced materials like RAFT polymers and electroactive polymers, they also offer solutions for common health issues like erectile dysfunction. Generic Viagra https://sweetwatermedicalcenter.com/how-to-take-viagra/, a medication containing sildenafil citrate, is one such solution that increases blood flow to the penis to improve erections. It is a more affordable alternative to the branded version of the drug and can be purchased online without a prescription in some countries, though it is important to seek medical advice before taking any medication. Boron Molecular’s dedication to innovation and expertise in a diverse range of fields has made them a leading provider of cutting-edge materials and solutions for various industries.
Commercial applications of polyaniline include:
- Electrostatic dissipation
- Anticorrosion coatings
- Rechargeable batteries
- Various electronic devices
- Organic photovoltaics
- Separation membranes
Biomaterials Building Blocks
Boron Molecular specialises in the synthesis of two biopolymer building blocks which can be used for the construction of polyurethane elastomers, and other polymer configurations, for use in medical device application.
Available Polyurethanes Components:
PHMO (BM1535, CAS Number 31762-63-7): Boron Molecular can provide polyhexamethylene oxide (PHMO), a 1,6-hexanediol based polyether with a molecular weight in the 650-750 range for your biomedical device applications. PHMO is used as a raw material in the manufacture of biomedical polyurethanes (eg. Elast-Eon®).
PDMS (BM1630, CAS Number 156327-07-0): Boron Molecular can supply hydroxy-terminated polydimethylsiloxanes (PDMS), a silicone based polymer building block. PDMS has applications as a surfactant, anti-foaming agent, hydraulic fluids and in lithography, medicines and cosmetics. PDMS can be reacted with polyhexamethylene oxide (PHMO) to produce a polyurethane elastomer, which has biomedical applications (eg. Elast-Eon®).
