The present invention is directed to the use of multiaxially oriented (e. g. , biaxially) thermotropic polymers as a substrate material for the preparation of printed wire boards (PWB). In preferred embodiments, the PWB of the present invention comprises a generic, high density, organic multilayer PWB comprising XYDAR. RTM. and/or VECTRA. RTM. films, capable of being employed as a high density leadless perimeter and in grid array ceramic chip packages.

The present invention is based upon the discovery that ordered polymers, such as PBzT, can be readily formed into tubular structures which retain a biaxial orientation imparted thereto during processing, and that these rigid, high-stiffness tubular components can exhibit near zero coefficient of thermal expansion (CTE). Zero CTE materials are not adversely affected by vast swings in temperature, e. g. , from very hot to very cold in short periods of time, nor are they adversely affected by long term exposure to either temperature extreme. The tubular components of the present invention thus represent a revolutionary advance in space based hardware, as the extreme temperatures experienced there will not affect rigidity of structures built using these components.

Improved belt for a charged particle separation system, the belt being an extruded article made from a host polymer and additive composition. The host polymer and additive are selected to yield a belt with tailored properties such as wear resistance, creep, coefficient of friction, and charging properties.

There is described a method for making visible range dichroic polarizer material comprising a uniaxially stretched film of polyvinyl alcohol stained with iodine and treated with a borating solution containing a zinc salt. The method comprises the steps of staining a uniaxially stretched sheet of polyvinyl alcohol and further stretching the stained sheet while it is being treated with a borating solution containing a zinc salt. High efficiency visible range dichroic polarizer elements having good neutrality, very high extinction and high transmittance can be made according to the method.

This invention relates in general to the formation of multiaxially (e. g. , biaxially) oriented films from high molecular weight lyotropic or thermotropic polymers (homopolymers, copolymers, and the like), wherein due to the processing conditions employed, the films have a controlled molecular orientation. The films of the present invention are preferably prepared from rod-like extended-chain, aromatic- heterocyclic polymers. These polymers generally fall into two classes; first, those that are modified in solution form, i. e. , lyotropic liquid crystalline polymers; and second, those that are mod STATEMENT OF GOVERNMENT INTEREST Funding for the present invention was obtained from the Government of the United States by virtue of Contract Nos. F33615-83-C-5120 and N00164-87-C-0050, from the Departments of the Air Force and the Navy, respectively. Thus, the Government of the United States has certain rights in and to the invention claimed herein.
