    摘要： A class of soluble poly(aryletherimides) (PAEIs) having flexible backbones, useful in the manufacture of polymeric optical films are disclosed. The poly(aryletherimides) are dissolved in organic solvents, such as ketones and ketone solvent mixtures and coated on variety of substrates such as triacetyl cellulose (TAC), to form clear thin-layer films which display negative birefringence. The thin films can serve as compensation layers in liquid crystal displays (LCDs), and can be combined with other types of optical films, such as polarizers, brightness enhancement films, or other compensation films, to from multi-layered films that are especially useful in the manufacture of LCDs.

    摘要： The invention provides a drawn and/or crimped fiber comprising a biodegradable polymer, such as polylactic acid, wherein the drawn and/or crimped fiber exhibits a storage-stable tenacity that does not decrease from an initial tenacity upon manufacture by more than about 10% after storage for 120 days in ambient conditions. The polymer composition used to form the fiber may comprise a softening agent. The fiber can be a drawn and crimped bicomponent fiber that is helically self-crimped and which comprises a first biodegradable polymer component and a second biodegradable polymer component, wherein the first polymer component and the second polymer component exhibit different polymer morphology such that each polymer component will undergo a different extent of longitudinal shrinkage upon application of heat. The outer surface of the fiber may carry a water-repellant coating. The invention also provides a method of forming a drawn and/or crimped fiber exhibiting storage-stable tenacity.

    摘要： A new class of pyrylium salts and process for the manufacture, as well as the use of the new pyrylium salts as polycondensation components for a new class of polypyridinium salts and a new class of conducting polypyridinium salts manufactured by doping the polypyridinium salts with a conducting dopant is described. The new polypyridinium salts and their conducting doped analogs according to this invention are stable positively charged polymers resistant to base attack and are distinguished by water insolubility making them ideally suited as a metal anti-corrosion coating, stable in basic media making them ideally suited for separation membranes for anions, and as excellent, thermally and chemically stable conducting polymers when doped ideally suited for making electrically conducting materials and as redox catalysts.
