General Description

METHACRYLOXYMETHYLTRIMETHOXYSILANE is a chemical compound used in the production of adhesives, coatings, and sealants. It is a silane coupling agent, which means it is used to improve the adhesion between organic materials and inorganic materials. Its methacryloxy group allows it to be easily incorporated into organic polymers, while its silane group enables it to bond with inorganic surfaces such as glass, metal, and ceramics. This makes it a versatile and important component in the formulation of various industrial and construction materials. Additionally, METHACRYLOXYMETHYLTRIMETHOXYSILANE is also used in the manufacturing of dental materials and as a surface modifier in the automotive and electronics industry.

(Trifluorosilyl)methyl 2-methylacrylate: Synthesis, experimental and theoretical studies

The novel stable organosilicon compound containing pentacoordinated silicon atom, named as (trifluorosilyl)methyl 2-methylacrylate, was synthesized and fully characterized including single-crystal X-ray diffraction. The asymmetric unit of the title compound contains two independent molecules, one of which adopting the s-cis configuration and the other has the s-trans configuration with respect to the C[dbnd]O and C[dbnd]C bonds. In the crystal, conformers form cis- and trans-dimeric pairs due to tetrel-bonding interaction and hydrogen bonds C[sbnd]H··· F. Energetic and geometric characteristics for these dimers were calculated by DFT methods at M06-2X/6-311G(d,p) level of theory using QTAIM analysis. The calculations in the polar medium (DMSO) for two dimeric fragments of crystal packing were performed with Onsager self-consistent reaction field method.

COSMETIC TREATMENT METHOD COMPRISING THE APPLICATION OF A COATING BASED ON AN AEROGEL COMPOSITION OF LOW BULK DENSITY

The present invention relates to a cosmetic treatment method comprising the formation of a coating on keratin fibres characterized in that it comprises: 1) the preparation of an aerogel precursor composition comprising:—at least one organic solvent chosen from acetone, C1-C4 alcohols, C1-C6 alkanes, C1-C4 ethers, which may or may not be perfluorinated, and mixtures thereof and at least one precursor compound that contains:—at least one atom chosen from silicon, titanium, aluminium and zirconium,—at least one hydroxyl or alkoxy function directly attached to the atom chosen from silicon, titanium, aluminium and zirconium by an oxygen atom, and,—optionally an organic group directly attached to the atom chosen from silicon, titanium, aluminium and zirconium by a carbon atom, 2) the removal of the solvent or solvents resulting in the formation of an aerogel composition having a bulk density less than or equal to 0.35 g/cm3, 3) the application to the keratin fibres of the aerogel composition resulting from step 2) or of the aerogel precursor composition resulting from step 1). Advantageously, the molar ratio between the precursor compounds and the solvent is at most 1/20.

The Hydrolysis/Condensation Behaviour of Methacryloyloxyalkylfunctional Alkoxysilanes: Structure-Reactivity Relations

Various methacryloyloxymethylalkoxysilanes have been synthesized by nucleophilic substitution reactions starting from chloromethylalkoxysilanes under phase transfer catalysis conditions. The compounds thus obtained show an exceptionally high degree of reactivity with regard to hydrolysis and condensation both under acidic as well as under basic conditions compared to the established 3-methacryloyloxypropyltrimethoxysilane. A mechanistic model for this high reactivity by intramolecular activation is discussed.
