ABSTRACT:
The invention relates to a method for the preparation of a siloxane-based elastomer composition comprising at least one elastomer, said elastomer composition comprising poly(alkylene oxide) groups present in the elastomer as alkoxy-terminated grafts of polysiloxane units and linked to the polysiloxane units by silicon-carbon bonds wherein at least one vinyl functional polymer component is crosslinked in the presence of a peroxide catalyst.
