functional monomers: chemical moieties

DATE

October 2017

SPECIFIC POLYMERS research activity is based on organic, polymer and material chemistry. The conception and design of tomorrow’s materials always start with the development of innovative functional monomers bearing the specific moiety that will bring added-value in your application.

New Functional Monomers

AcSEMA
.

2-(acetylthio)ethylmethacrytale (AsSEMA) is a new monomer bearing an acetyl protected thiol ligand moiety for quantum dots nanoparticles. It was used recently for the synthesis of smart nanogels and hydrogels.

CBAAm
.

This monomer contains zwitterionic functional groups of interest for various analytical and biomedical applications. For instance, it allows to prepare ultra-low fouling or antimicrobial coatings.

D,L-homocysteine Thiolactone Acrylamide

This monomer is bearing a thiolactone functionalities that garnered significant attention as a powerful post-polymerization modification function to mutlifunctional polymeric materials. For instance, aminolysis or thiol-Michael modifications can be achieved.

Bromine-Containing Methacrylates

Tribromoethyl Methacrylate

(Trimethylbromide)methyl Methacrylate

Bromine containing monomers are of great interest for dental materials. Indeed, such materials contain radiopacifying fillers of high Refractive Index (1.51 – 1.61) and it is important that polymer matrix exhibit RI in the same range. Bromine containing monomers have been shown to exhibit radiopaque properties due to their high electronic densities and can be polymerized by UV-polymerization.

Boronic-Containing Monomers

Phenylboronate Acrylamide

Boronic Acid Neopentylglycol Ester Ethyl Methacrylate

Boronic-containing polymers have been used in a number of applications in the biomedical fields, such as saccharide responsive hydrogels, polymer glucose sensors, cell capture, enzymatoic inhibition and site-specific radiation therapy. The boronic acid moiety is well-known for both its Lewis acidity and corresponding complexation with electron donating moieties. All our boronic acid monomers can be protected in order to remove adverse effects of the boronic acid during synthesis or polymerization steps.

Renewable Monomers

(4-Methyl)coumarin-7-yl Methacrylate

Vanillin Methacrylate

Vanillin Styrene

Vanillin Hydroxypropyl Methacrylate

There is an increasing demand for monomers and polymers derived from natural sources in order to reduce materials carbone footprint. For many years, SPECIFIC POLYMERS develops and supplies vanillin based methacrylates (SP-68-013, SP-68-025) and styrenic monomers (SP-68-026). We are currently developing a new range of renewable terpenes based methacrylate and acrylate monomers (SP-49-016). Terpenes derived from citrus or wood waste and are already available at industrial scale. All monomers presented in this section exhibit post-reticulable moieties of interest for thermoset materials synthesis.

Functional Styrenic Monomers

We have also developed other interesting functional styrenic monomers. Firstly, styrene PEG can be used to prepare amphiphilic graft copolymers by free radical polymerization. In addition, lateral PEG chains of different length can be provided. Secondly, cyclocarbonates can be used as crosslinking moieties for synthesis of isocyanate-free polyurethane thermoset materials. Thirdly, imidazole is a functional group of interest in the biomedical field since it can have biophysical interactions with drugs and proteins.

Alcoxysilane vs. Phosphonic Acid Linking Groups

SPECIFIC POLYMERS research activity mainly focus on organic polymers based materials. Nevertheless, the problematic of interactions between organic and inorganic matters has been the subject of numerous studies. Indeed, in most of the cases, the chemical nature of interaction between the inorganic particles and the polymer drives the performance of the resulting system.
