Cured, thermoset plastic articles derived from scrap polyurethanes are disclosed. The polyurethane is converted to a liquified mixture containing digested polyurethane and cyclic, unsaturated anhydride. A Lewis acid then catalyzes insertion of the cyclic, unsaturated anhydride into the polyether backbone of the polyurethane to give a liquid, unsaturated resin. The unsaturated resin can cured with ...

Dispersions of hydrophobic substance eg resin emulsions, usually having a relatively low average particle size can be continuously and speedily prepared by feed a hydrophobic substance in the liquid state into at least two static mixers, arranged in a series. The resin is introduced at a temperature above 50 degrees C but below its degradation temperature of hydrophobic substance and water under p...

The co-ordinated use of L-carnitine or acyl L-carnitines and valproate allows a dramatic decrease in seizure frequency to be observed in epileptic patients.

According to the invention, in the moulding cavity (22) of the mould (20) employed, a shell (casing) (34) made of synthetic material is provided in order to grip, at least partially, the fragile part of the insert. Application, in particular, to the overmoulding of an electric light bulb.

A procedure is described for a rust-proofing surface treatment of steel parts, especially for vehicle filter parts or components. This procedure consists of phases of washing, preheating, nitriding and steam oxidation of the batch to treat which takes on a black colouring as a result of the magnetite generated by the process. This process is also characterised by the particular composition of the ...
