Dry liquid concentrates allow carbon nanotubes to be dispersed in rubber formulations under standard rubber processing conditions. The incorporation of carbon nanotubes can enhance the physical properties of the resulting rubber material in many ways, including creating a more resilient rubber which resists abrasion, tearing, and chipping.

The present invention relates to a super absorbent polymer having more improved absorbency under pressure and liquid permeability, and a method for producing the same. The super absorbent polymer comprises a base polymer powder including a cross-linked polymer of a monomer containing a water-soluble ethylenically unsaturated compound or its salt; and a surface cross-linked layer that is formed on the base polymer powder and is further cross-linked from the cross-linked polymer, wherein a glass hollow particle having a micron-scale particle size is included on the surface cross-linked layer.

Heat-expandable microspheres with high encapsulation efficiency of a blowing agent and good heat-expansion performance, a process for reproducibly producing the heat-expandable microspheres and application thereof are provided. The heat-expandable microspheres comprise essentially a thermoplastic resin shell and a blowing agent encapsulated therein, and contain not more than 500 ppm of silicon, not more than 350 ppm of aluminum and not more than 600 ppm of the total of the silicon and aluminum. The heat-expandable microspheres retain at least 70% of the blowing agent encapsulated therein at the temperature which is the average of their expansion-initiation temperature and maximum expansion temperature.

Bonding dissimilar materials of medical device components can be carried out by applying an adhesive on at least one surface of two components which are composed of dissimilar materials and contacting the surfaces and exposing the contacted surfaces to heat and/or irradiate the adhesive to cure the adhesive and bond the surfaces. One medical component, e.g., medical tubing, can be composed of a non-polar, polyvinyl chloride free thermoplastic polymeric material and the other medical component, e.g., a medical connector, can be composed of polyacrylate, polyacrylonitrile, acrylonitrile-butadiene-styrene (ABS), methyl methacrylate-acrylonitrile-butadiene-styrene (mABS), polyester, and/or a polycarbonate material. The adhesive formulation can include: (a) a polyolefin oligomer having reactive acrylate groups and alkenyl groups, (b) an initiator, and optionally (c) a solvent.

Described a coagulant formulation for use in the preparation of a material that is formed by dipping, wherein the formulation includes a lipophilic and/or amphiphilic polymeric ionophore:ion complex wherein the polymeric ionophore is a hydrophilic and/or amphiphilic polymer and wherein the polymeric ionophore:ion complex imparts antimicrobial and/or antiviral properties to the material.
