Abstract
A method for synthesizing a modified polymer comprising epoxide groups along the polymer chain, by a hydrosilylation reaction of the unsaturations with a hydrosilane bearing an epoxide function in the presence of a suitable catalyst is provided. The method is simple, reproducible and able to be used on an industrial scale, and makes it possible to obtain high grafting yields, since they may reach 100%.
