The invention relates to a composition containing at least one catalyst (C1) containing at least one atom of an element (M1) chosen from: Al, Sc, Ti, Mg, Mn, Fe, Co, Ni, Cu, Zn, Zr, Sn, Hf, Pb, Si, Sb and In; a catalyst (C2) comprising at least one atom of an element (M2) chosen from alkali metals and alkaline-earth metals; a thermosetting resin and/or a hardener for a thermosetting resin. The invention also relates to the use of this composition for rendering a resin which is in the thermoset state hot-deformable and nevertheless free of any residual stress after the deformation thereof; such a resin will advantageously retain its shape even if it is subsequently subjected to high temperatures. The invention relates, moreover, to kits for preparing the composition, to a thermoset-resin-based object obtained from a composition of the invention, to a process for manufacturing objects, to a process for hot-deformation of objects and to various possible uses of the compositions and objects of the invention.

Metallated aminosilane compounds for use as functional initiators in anionic polymerizations and processes for producing an aminosilane-functionalized polymer using the metallated aminosilane compounds to initiate anionic polymerization of at least one type of anionically polymerizable monomer. Preferred use of the metallated aminosilane compounds results in rubber compositions for use in tires comprising an aminosilane functionalized polymer.

According to an embodiment of the present invention, there is provided a method of preparing a rubber composition, which includes (a) synthesizing a living polymer by solution polymerization of a monomer mixture including a conjugated diene-based monomer in the presence of a first catalyst; (b) reacting some ends of the living polymer with a coupling agent; (c) reacting the remaining ends of the living polymer with an organotin halide compound to prepare an end-modified conjugated diene-based polymer solution; and (d) adding a second catalyst and a conjugated diene-based monomer to the end-modified conjugated diene-based polymer solution to induce solution polymerization.
