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.

A coated particle according to the present invention is a coated particle containing a conductive metal-coated particle having a metal film formed on a surface of a core material, the conductive metal-coated particle coated with an insulation layer containing a polymer, wherein the insulation layer has a phosphonium group.

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 a controlled degree of internal crosslinking and thereby having simultaneously improved basic absorption capacity and absorbency under pressure, and a method for producing the same. The super absorbent polymer may comprise 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 in the cross-linked structure of the cross-linked polymer of the base polymer powder.

Hollow resin particles, a production process for producing the same and application thereof. The hollow resin particles include a thermoplastic resin shell and a hollow part surrounded by the shell. The thermoplastic resin is a polymer produced from a polymerizable component containing 0.6 to 3.0 wt % of a crosslinkable monomer having at least two polymerizable carbon-carbon double bonds per molecule and 97 to 99.4 wt % of an uncrosslinkable monomer having one polymerizable carbon-carbon double bond per molecule. A blowing agent is encapsulated in the hollow resin particles. The blowing agent contains 50 to 100 wt % of an organic compound having a vapor pressure higher than 100 kPa at 25 C. Further, the encapsulation ratio of the blowing agent ranges from 3 to 13 wt % of the hollow resin particles.

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.
