One of the problems is to provide a solvent composition which has a little adverse effect on the global environment and has excellent stability when a compound having a perfluoropolyether (PFPE) group is in a solution state. In an embodiment, the problem is solved by providing a solvent composition for dissolving a compound having a perfluoropolyether (PFPE) group includes Z-1,2-dichloro-3,3,3-trifluoropropene (1223xd(Z)) as a main component.

Disclosed herein is a polymeric article comprises an elastomeric layer comprising cured synthetic polyisoprene particles that comprise a rare earth catalysed polyisoprene. The polyisoprene particles may comprise sulfur crosslinks and/or may be pre- vulcanized. Also disclosed herein are methods for producing polymeric articles comprising an elastomeric layer comprising cured synthetic polyisoprene particles that comprise a rare earth catalysed polyisoprene.

A drag reducing composition comprising at least one non-polyalphaolefin polymer having an average particle size in the range of from about 5 to about 800 micrometers. The non-polyalphaolefin polymer can initially be formed via emulsion polymerization. The initial polymer particles can then be at least partially consolidated and then reduced in size and suspended in a carrier fluid. The resulting drag reducing composition can be added to a hydrocarbon-containing fluid to decrease the pressure drop associated with the turbulent flow of the hydrocarbon-containing fluid through a conduit.

Provided is a laminated sheet processing method capable of easily separating a base material for forming many kinds of laminated sheets, such as pressure-sensitive adhesive tapes, release films, and antistatic films, and a functional layer such as a pressure-sensitive adhesive layer, a release layer, and an antistatic layer laminated on the base material, from each other, at low cost. Furthermore, a laminated sheet processing device used for such a laminated sheet processing method is provided. The laminated sheet processing method according to an embodiment of the present invention is a method for processing a laminated sheet including a base material layer and a functional layer, and includes a step (I) of applying a separation liquid to a surface of the functional layer.

A method of making a carbon fiber having on its surface a partially cured sizing agent, the method comprising covalently binding on the surface of said carbon fiber a sizing agent comprised of an epoxy resin, and partially curing said sizing agent by contact thereof with a curing agent such that at least a portion of epoxide groups remain uncrosslinked on said surface, which corresponds to a curing degree of epoxide groups of no more than about 0.6, and further comprising reacting at least a portion of said epoxide groups with a bifunctional molecule that contains first and second reactive groups, the first reactive group being reactive with and forming a covalent bond with the epoxy group, and the second reactive group being unsaturated and accessible for reaction with a carbon-carbon double bond of an unsaturated resin via a vinyl addition reaction.

The invention relates to a process for the production of prefoamed poly(meth)acrylimide (P(M)I) particles which can be further processed to give foam mouldings or composites. A feature of this process is that a polymer granulate is first heated and thus prefoamed in an apparatus by means of IR radiation of a wavelength suitable for this purpose. Said granulate can be further processed in subsequent steps, e.g. in a press mould with foaming to give a moulding or a composite workpiece with foam core.

Polystyrene-phenolic foam composites and precursor compositions are disclosed. The composites exhibit excellent flame resistance properties and may be suitably prepared in standard expanded polystyrene processing equipment.

Provided are a superabsorbent polymer having a high bulk density value and showing a reduction in unpleasant odors which may be caused by various additives included in a preparation process while basically maintaining excellent absorption performance and absorption rate, and a preparation method thereof.
