Usage

General Description

(Methacryloxymethyl)methyldimethoxysilane is a chemical compound that combines the functionality of a methacrylate group and a silane group. It is commonly used as a coupling agent in the production of reinforced plastics and composites, as well as in sealants, adhesives, and coatings. When mixed with polymers, it enhances the adhesion and bonding between the polymer and glass or metal substrates, leading to improved mechanical properties and long-term durability of the resulting materials. Additionally, it can also act as a crosslinking agent in polymerization reactions, providing improved chemical and weather resistance to the final products. Overall, (Methacryloxymethyl)methyldimethoxysilane plays a crucial role in enhancing the performance and longevity of various polymeric materials and their applications.

METHOD FOR PRODUCING (METH)ACRYLOSILANES

The invention relates to a method for producing silanes (S) of the general formula (1); (R1)2C═C(R1)C(O)O—(R2)—Si(R3)z(OR4)3-z, starting from a alkyl halide silane (S1) of the general formula (2); X-(R2)-Si(R3)z(OR4)3-z, and a salt (S2) of an unsaturated organic carboxylic acid of the general formula (3); Mw+[(R1′)2C═C(R1)C(O)O?]w, where R1, R1′, R2, R3, R4, X, Mw+, w and z have the meanings given in claim 1, wherein one or more components (L) having a boiling point below the boiling point of the alkyl halide silane (S1) are at least partially removed from the reaction mixture, partial mixture or individual reactant components by distillation before or during the reaction of components (S1) and (S2).

Process for stabilizing unsaturated organosilicon compounds

A process for stabilizing organosilicon compounds bearing unsaturated groups during their preparation, distillation, and/or storage, the organosilicon compounds bearing unsaturated groups having been obtained by reacting a haloalkylsilane with a salt of an unsaturated organic acid, by adding one or more compounds of the formula I wherein R1 and R2 are identical or different linear or branched C1-20 alkyl, and the radicals R3 are identical or different and are hydrogen or linear or branched alkyl radicals having 1-20 carbon atoms.
