An ultrastretchable polymer material is prepared starting from polyolefine particles with a low entanglement density and a weight average molecular weight (MW) higher than 400,000, the particles being densified to a coherent material together with a process auxiliary material at an elevated temperature, but below the melting point of the pure polyolefine. From this ultrastretchable material, objec...

An improved method for dispersing an inorganic pigment uniformly in polyphenylene ether resins. A polyphenylene ether composition having an inorganic pigment uniformly dispersed therein is obtained by intimately mixing a polyphenylene ether resin and the inorganic pigment in a weight ratio of from 0.5:1 to 2:1 by a high-speed mixer to form a pre-blend, and then mixing the pre-blend intimately with...

The invention relates to apparatus for detecting the stuck point of a conduit, such as drill pipes, in a borehole while eliminating any stress on the detection means during the measurement. A two-part body member is suspended from a cable with the two parts (23 and 24) mounted movably with respect to each other. Each part is anchored independently in the drill pipes and movements between these par...
