A fiber having increased cut resistance is made from a fiber-forming polymer and a hard filler having a Mohs Hardness Value greater than about 3. The filler is included in an amount of about 0.05% to about 20% by weight. In preferred embodiments, the fiber-forming polymer is poly(ethylene terephthalate) or a liquid crystalline polyester comprising monomer units derived from 6-hydroxy-2-naphthoic acid and 4-hydroxybenzoic acid. Preferred fillers include tungsten and alumina.

The process for forming a microporous polymeric semi-crystalline film, involving the steps of cold compressive extruding a precursor film, preferably in a biaxial fashion, so as to compress the film by a factor of about 2 to 1 to about 10 to 1, stretching the film by about 100 to about 500 percent, preferably in a biaxial fashion, and heat annealing either before, during, or preferably after the stretching step at a temperature up to the alpha transition temperature of the polymer for a time sufficient to maintain the microporous character of the final film.

Optical media formed from a water soluble polymer and liquid crystal forming amphiphile are disclosed and claimed. The polymer and amphiphile are cast into a film which exhibits an optical axis of symmetry perpendicular to the film surface.

Self-assembled optical media

This invention provides novel self-assembled multilayer organic thin films including an azo-benzene chromophore which initially appear substantially amorphous when viewed perpendicular to the film surface, but are subsequently treated with a laser in selected areas so that such portions exhibit photo-induced birefringence.

This invention provides novel polymers that contain, in their side chains, 4-benzoyloxyphenyl moieties. These polymers have utility as coating to protect polyester materials from damage due to ultraviolet radiation.

A process is provided for modifying the properties of a hydrophobic microporous membrane which includes the steps of first providing a hydrophobic microporous membrane, treating it with a surfactant to render the membrane hydrophilic, wetting the membrane with an aqueous solution of a polyol such as polyvinyl alcohol (PVA) and divinyl sulfone (DVS) or a precursor thereof, washing the membrane with water to displace the polyol/DVA from the exterior of the membrane while retaining it in the pores of the membrane, and crosslinking the polyol/DVS into an aqueous gel to yield a hydrophilic microporous membrane having pores filled with an aqueous polyol/DVS gel, the exterior of the membrane being unobstructed by gel. The modified membranes produced according to the process are useful in carrying out chromatographic separations.

In one embodiment this invention provides a process for preparing a holographic composition which is a thin film of polyphenyl acylate polymer which has a photo-Fries molecular rearrangement corresponding to a recorded refractive index pattern induced by exposure to a coherent light interference pattern.

Polymeric direct imaging holographic compositions

A pore modified microporous membrane is disclosed which is made by the process of incorporating a polymerizable vinyl monomer within the pores of a microporous membrane followed by polymerization to secure the resulting polymer within the pores. The process is particularly suitable for modifying a hydrophobic microporous membrane with a hydrophilic polymer, as occurs for example when polyacrylic acid is secured into the pores of a polypropylene microporous membrane. In further applications of the present invention, the inventive method may be used to produce liquid membrane supports for use with or without active carriers.
