Method of producing porous molded body
A molding device produces a porous film from a molding material which is an emulsion. In a case where a volume of a dispersed phase is X1 and a volume of a continuous phase is X2, the molding material has a value of X1/(X1+X2) within a range of 0.5 or more and 0.9 or less. In the molding material, a specific gravity of the dispersed phase is greater than a specific gravity of the continuous phase. The molding material includes a water phase containing a curable compound as the continuous phase, and forms a liquid film on a support. Thereafter, the curable compound in the liquid film is cured. After curing, the dispersed phase is removed.
Thermoplastic polymer composition, method for preparing same and vibration-damping device incorporating same
The invention relates to a thermoplastic polymer composition comprising polyamides, its preparation method and a device for a motor vehicle capable of damping vibrations.

The composition has, after “RH50” conditioning, maximum tan delta values according to ISO 6721-5 between 60-90° C. and 1-3000 Hz, with (i) tan delta >4.20% at 60° C. and/or (ii) tan delta >4.00% at 80° C. and/or (iii) tan delta >3.80% at 90° C.
In-situ hydrophobically modified aramid nano aerogel fiber as well as preparation method and uses thereof
An in-situ hydrophobically modified aramid nano aerogel fiber as well as a preparation method and uses thereof are provided. The preparation method includes: providing an aramid nano spinning solution; preparing a hydrophobically modified aramid nano aerogel fiber by using a spinning technology, wherein the coagulating bath adopted by the spinning technology includes a first organic solvent and a halogenated reagent including a monochloroalkane, a monochloroalkane, a dibromoalkane, a dichloroalkane and a trichloroalkane; and then drying to obtain the in-situ hydrophobically modified aramid nano aerogel fiber. The in-situ hydrophobically modified aramid nano aerogel fiber has a unique three-dimensional porous network structure, low heat conductivity, high porosity, high tensile strength and elongation at break, a certain spinnability and structure stability, and can be applied to the field of textiles. A fabric knitted with the hydrophobic fibers has a self-cleaning ability.
Flexible pipe and coupling therefor
Construction of a sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner liner layer of the flexible pipe or hose may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each be comprised of a semi-crystalline thermoplastic material. Furthermore, a reinforcement material may be provided in the inner liner layer.

ACTIVATING SURFACES FOR SUBSEQUENT BONDING
A method of activating a surface of a plastics substrate formed from: (a) polyaryletherketone such as polyether ether ketone (PEEK) polyether ketone ketone (PEKK), polyether ketone (PEK); polyether ether ketone ketone (PEEKK); or polyether ketone ether ketone ketone (PEKEKK); (b) a polymer containing a phenyl group directly attached to a carbonyl group, for example polybutadiene terephthalate (PBT) optionally wherein the carbonyl group is part of an amide group, such as polyarylamide (PARA); (c) polyphenylene sulfide (PPS); or (d) polyetherimide (PEI); for subsequent bonding,
the method comprising the step of exposing the surface to actinic radiation wherein the actinic radiation: includes radiation with wavelength in the range from about 10 nm to about 1000 nm; the energy of the actinic radiation to which the surface is exposed is in the range from about 0.5 J/cm.sup.2 to about 300 J/cm.sup.2.
Hard to bond substrates are then more easily subsequently bonded for example using acrylic, epoxy or anaerobic adhesive.
