Abstract: A method of making a three-dimensional film structure having controllable contact properties comprises making separable surface elements on a top portion of a film structure and stretching the film structure to separate the separable surface elements, thereby obtaining a desired surface structure which delivers a certain contact property such as a pressure sensitive adhesive property. The separable surface elements are provided using a cut film surface, a stemmed film, or a layer of particles.

Abstract: A method for temporary surface protection or surface modification using a sheet material is disclosed. In the inventive method, a selectively activated adhesive is provided on one side of a three-dimensional sheet material for maintaining the sheet material in place for uses such as the dental bib, tool tray liner, or providing desired optical effects on a surface to which the sheet material has been adhered.

Abstract: Fibers and microfibrillated articles are provided by imparting fluid energy to at least one surface of a highly oriented, voided, melt-processed polymeric film. The fibers and microfibrillated articles are useful as tape backings, filters, thermal and acoustical insulation and as reinforcement fibers for polymers or cast building materials such as concrete.

Abstract: In an acrylonitrile based retarder, relatively uniform performance is obtained as the angle of incidence varies over a wide range. A toughening material may be blended with an acrylonitrile based polymer to facilitate processing of a retarder and improve mechanical properties of the retarder without compromising the optical performance. A rubber-modified acrylonitrile based retarder which provides relatively uniform wide angle can be fabricated using conventional processing techniques. Such retarders are particularly suited for a number of specific applications which use relatively wide ranges of incidence angles.
