Abstract: Provided is a polymerizable composition including a mixture of at least one monomer which is capable of undergoing radical polymerization and which bears at least one polymerizable function, of at least one flexible dormant polymer block capable of generating at least one radical, and at least one free-radical generator derived from the decomposition of a photoinitiator. The composition may be used as a component of an adhesive, coextrusion binder, varnish, coating, resin for impregnating fabrics or woven materials, a composition suitable for printing on a flexible support or a composition suitable for 3D printing, for example.

Abstract: The present invention relates to filamentous polymer particles useful in oil, condensate or gas recovery from subterranean locations as hydraulic fracturing fluids, diverting fluids, fluids that make it possible to improve the distribution and the flow profiles of the fluids or products injected (referred to as conformance fluids) or permeability control fluids, sand control gravel pack placement fluids, acid fracturing fluids, and the like. These fluids are stimulation fluids injected in wells which serve also as producing wells for the hydrocarbons initially present in the subterranean formations.
