| titleOfInvention | Functionalisation (epoxidation) of silicones and use of said silicones as non-stick coatings |
| abstract | The invention relates to a method of preparing epoxidised POSs using a platinum-catalysed hydrosilylation reaction between an ethylenically-unsaturated epoxide, such as VCMX, and a hydrogenated POS of the MDD'M type with M = R3-SiO1/2, D = R2-SiO2/2, D' = RH-SiO2/2, wherein R = alkyl. The aim of the invention is to propose a method for the synthesis of epoxidised POS silicones by means of heterogeneous catalysis, which can be used to control and optimise the viscosity of the end product, i.e. to limit parasitic cationic polymerisation reactions caused by the opening of heterocylces, which can produce the partial or total gelling of the reaction mixture. Said aim is achieved by the invention which is characterised in that the hydrosilylation is performed in the presence of at least one inorganic non-nucleophilic base (NaHCO3) and, optionally, water. |
