Abstract

Isobutylene copolymers, cross-linkable under ambient humidity conditions, characterized by the presence of pendant functions containing a silyl radical, are prepared by a process comprising the preliminary formation of new copolymers of isobutylene with a triene containing a system of two conjugate double bonds in position 1,3 and at least one other double bond of vinyl type, followed by the silylation of the polymers thus produced by means of a silicon derivative chosen from those of formula (I) or (II): ##STR1##
