摘要： 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.

摘要： A group of compounds defined by the general formula (I) can be used to anionically initiate polymerization of unsaturated monomers. In the formula, M is an alkali metal atom, R1 is an aryl group having at least one OR2 substituent group where each R2 is a group that is nonreactive toward M, and R is a hydrocarbyl group. The subject initiators can be used in semi-batch and continuous polymerization processes, even those which are performed at elevated temperatures.
