METHOD FOR OBTAINING ORGANOPOLYSILOXANES WITH VINYL GROUP.

摘要

Described is the method and process for obtaining an organopolysiloxanase with vinyl groups (divnylpolysiloxane) resulting from an organopolysiloxane with OH functional groups in the end portions thereof (a, w, dihydroxypolysiloxane) and a vinylizing agent obtained from the dissolution of a cationic metallic-complex catalyst solved in a vinyl monomer. The obtained divinylpolysiloxane is applied to formulate corrosion protecting coatings where additional mechanical seals and resistance to temperatures under 270°C are required.
