    Abstract: The invention concerns a method (100) for recovering and/or recycling a bituminous product by means of pulsed power, the bituminous product comprising bitumen and elements to be separated, involving the following steps: supplying (101) a reactor (11) inside which at least two electrodes (13) extend with the bituminous product and a liquid medium of which at least one liquid component has Hansen solubility parameters δη, δρ and δd such that the bitumen is at least partially soluble in the liquid medium, the elements to be separated being insoluble, generating (102) a series of electromagnetic pulses between the electrodes (13) in the reactor (11) so as to produce, as a result of the power, the frequency and the switching time of the electromagnetic pulses, at least one shock wave and at least ultraviolet radiation, in such a way as to disperse and dissolve the bitumen in the liquid medium, and to separate the bitumen and the insoluble elements, the liquid medium preventing the reconstitution of the bitumen.

    Abstract: An installation (1) and method for treating composite products (2) based on thermoplastic material(s) for recycling purposes, the installation at least comprising means (3, 4, 4′, 5, 6) for heating, for reducing size, for crushing and for separating, said means being arranged to form at least one line (1′) for treating and extracting material(s) to be reused, operating as a continuous or intermittent flow, and regulated if necessary. The installation (1) is characterised in that the means (3) for heating and reducing size comprise at least one heated screw mixer, the crushing means comprise at least one roll crusher (4, 4′) comprising two rolling rollers (7 and 7′) that are heated and set into rotation in opposite directions, the separating means (5, 6) comprise at least one macroscopic separating means (5) in the form of a device for discharging macroscopic polluting particles present in the output (3′), and the separating means (5, 6) also comprise at least one microscopic separating means (6).

    Abstract: The invention relates to polyurethane resin compositions and, in particular, stable, ready-to-use polyurethane resin compositions comprising: a masked polyisocyanate having formula (I), wherein B represents alkyl and A represents a group comprising a number of isocyanate functions of between 1.5 and 2.2, preferably between 1.5 and 2.1 and, more preferably, between 1.5 and 2; or a masked pre-polymer that is the product of a reaction between the above-mentioned masked polyisocyanate and a polyol having between 1.5 and 3 OH functions and a molecular mass of between 900 and 3,000 g/mol, in a ratio such that the number of NCO functions of the masked polyisocyanate in relation to the number of OH functions of the polyol is between 1.5 and 2.5 approximately; or a mixture of the aforementioned masked polyisocyanate and masked pre-polymer. The invention also relates to the use of the masked polyisocyanate in order to form a masked pre-polymer by reacting said masked polyisocyanate on a polyol, and to the use of a masked polyisocyanate and/or a masked pre-polymer in polyurethane resin compositions.

    Abstract: The present invention relates to a polymerisable plasticiser formed by a hydrocarbon chain, one end of which bears more than one isocyanate function, said hydrocarbon chain comprising and/or being substituted by an aromatic ring and/or an aliphatic ring and/or said hydrocarbon chain is substituted by at least two hydrocarbon chains that can comprise an unsaturation, and the number of isocyanate functions being strictly greater than 1, preferably greater than 1.2, and, more preferably, grater than 1.5 but less than or equal to 2.2. The invention also relates to liquid polyurethane resin compositions and, in particular, stable, ready-to-use liquid polyurethane resin compositions comprising said plasticiser. The invention further relates to methods for replacing all or part of the exogenous plasticiser and/or solvent in a polyurethane resin by adding said polymerisable plasticiser.
