The adhesion of highly oriented polyolefin objects, in particular polyethylene filaments, to e.g. polar, polymer matrices is improved by contacting the surface of the object with a solvent for 0.5-2 minutes at a temperature above the dissolution point of the polyolefin.

The adhesion of polyolefin objects, in particular highly oriented polyethylene filaments, to, for instance, polar matrices is improved by oxidizing the surface of the objects and then treating it with a solution of a silane compound, a titanate or a chromium complex.

Porous membrane is made of polyvinylidene fluoride and has a finely porous surface. A surface treatment is applied to render the porous surface uniformly hydrophilic and the reflection spectrum of the surface in this visible region is specified to be the same before and after the surface treatment. - In the surface treatment, oxidising agents introduce polarising gps. into the molecule so that the...

The invention relates to a sound-damping element (1), in the outer layers (3, 5) of which U-profiles (6-11) are inserted. The U-profiles (6-11), preferably made of steel, increase the sound-damping value of the element from 39 dB to 44 dB. Gluing the U-profiles (6-11) into the outer layers (3, 5) of the element moreover ensures better rigidity of the element (1).
