A fluorinated copolymer composition includes a thermoplastic resin A and a fluorinated elastomer B dispersed within thermoplastic resin A. Thermoplastic resin A has a shear stress (.sub.A) of greater than 0.11 MPa when measured with a capillary rheometer at a shear rate of 243 sec.sup.1 and at 360 C. in accordance with ASTM D3835. Fluorinated elastomer B dispersed within thermoplastic resin A has an average dispersed particle size of less than 50 m.

A thermoplastic product, such as a film, tubing, sheeting, and a profile with a cross-section, is made by a process including extruding a melt-blended mixture comprising a thermoplastic polymer and a fluorocarbon additive through an extruding die. The thermoplastic polymer and the fluorocarbon additive are substantially homogenously distributed in the melt-blended mixture before extrusion. Upon cooling, the extruded product forms into a solid thermoplastic product comprising the thermoplastic polymer and the fluorocarbon additive and having a particular shape. The fluorocarbon additive has a lower surface energy than that of the thermoplastic polymer. As a result, a concentration of the fluorocarbon additive through a cross-section of the solid thermoplastic product is lower in the interior thereof and higher at the surfaces thereof. The solid thermoplastic product has a lubricity surface. The thermoplastic product having lubricity surfaces may be further flexible and/or elastic, or non flexible.

The present invention relates to a process for producing a molding made from blowing agent-containing foam comprising at least one fiber (F), wherein the at least one fiber (F) is partially introduced into the blowing agent-containing foam. The two ends of the respective fiber (F) that are not surrounded by the blowing agent-containing foam thus project from one side of the corresponding molding. The present invention also provides the molding as such. The present invention further provides a panel comprising at least one such molding, produced by the process according to the invention, and at least one further layer (S1). The present invention also provides for the production of the panels of the invention and for the use thereof, for example as a rotor blade in wind turbines.

Adhesive compositions are described that significantly improve the adhesion of polymer overmold compositions to metal substrates in polymer-metal junctions. The adhesive compositions include one or more poly(aryl ether) polymers, where each of the poly(aryl ether) polymers is, independently, a poly(aryl ether sulfone) polymer or a poly(aryl ether ketone) polymer. The overmold composition includes at least one poly(aryl ether ketone) polymer. Polymer-Metal junctions can be formed by, for example, dip-coating, spin-coating, extruding, or injection molding the adhesive composition and/or the overmold composition onto the metal substrate. Desirable applications settings for the polymer-metal junctions described include, but are not limited to electrical wiring.
