METHOD FOR PREPARING A STATISTICAL COPOLYMER BASED ON DIENE MONOMERS AND CYCLIC CARBOSILANE MONOMERS

摘要

The invention relates to a method for preparing a statistical copolymer based on diene monomers and cyclic carbosilane monomers. The method is characterised in that it comprises a step of copolymerisation in the presence of an anionic initiator in a reaction medium comprising a polar solvent, of at least one diene monomer and a cyclic carbosilane monomer of formula 1: (formula 1) wherein R1 and R2 are the same or different and each one is a C1-C5 alkyl group, a C6-C14 aryl group, or a C7-C11 aromatic alkyl group; R3 and R4 are the same or different and each one is a hydrogen atom or a C1-C5 alkyl group, a C6-C14 aryl group, or a C7-C11 aromatic alkyl group; and x is a whole number having a value of between 2 and 5, preferably 3.
