摘要： 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 modSTATEMENT OF GOVERNMENT INTERESTFunding 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.

摘要： An improved spandex fiber is provided that is particularly useful for use in tricot-knit fabrics with nylon yarns. The fiber is formed from a polyether-based spandex polymer made from a poly(tetramethylene ether) glycol of about 2,200 molecular weight which was capped with methylene-bis(4-phenylisocyanate) and the resultant product then chain extended with a diamine mixture of ethylene diamine and 2-methyl-1,5-pentanediamine in a molar ratio of about 70/30.

摘要： A simulated windowpane molding is achieved by inner and outer elongated members adapted to be placed in facing relationship upon opposite sides of a windowglass. Each elongated member has a flat surface adapted to fit flush against the windowglass. Magnetic holding structure in the form of a strip of plastic material containing a ferromagnetic powder, or a series of permanent magnets in bar form is disposed upon the flat surface of at least one elongated member. The flat surface of the other elongated member is either equipped with the same magnetic holding structure or material, such as iron, which is attracted by a magnet. When the two elongated members are brought into facing, mirror-image juxtaposition upon an intervening windowglass, the force of attraction between the two members is sufficient to cause the members to be securely positioned upon the windowglass.
