Thermoplastic multicomponent articles are shown wherein the components comprise a polymer matrix wherein one component contains at least one uniformly distributed substantially unreactive low molecular weight, guest molecule or compound which imparts different properties to the component.

Multilayered thermoplastic article with special properties

A rubber-polyester composite comprising a rubber and a core-and-sheath heterocomponent fiber wherein the fiber core is formed from a linear polyester derived from an alkyl glycol and an aromatic diacid, and wherein the fiber sheath is formed from a compatibilizing acid-terminated or isocyanate-terminated polyester. The fiber sheath may also be composed of a blend of a thermoplastic elastomer and the compatibilizing polyester.

Rubber-polyester composites including a functionally terminated

Bilayer filaments and fused cords thereof are described. The product is particularly useful for tire cord and filaments include a core of a partially crystalline, oriented polymer and a shell or sheath formed of a blend of robber and a relatively low melting polymer. A particularly preferred embodiment includes a poly(ethylene terephalate) core as well as a sheath of copolyester blended with poly(styrene-elastomer-styrene) elastomer.

Heterofilament and fused cord thereof

The present invention is generally directed to multi-component rubber-polyester composites including a sidechain containing copolyester as a compatibilizing component.

Rubber-polyester composites including a sidechain containing copolyester

Multi-component composites containing a linear polyester of an alkyl glycol and an aromatic diacid as one component, rubber as a second component, and a third component which is a compatibilizing polyester (polystyrene copolymer).

Provided is a method for stabilizing an optical recording medium containing a polycarbonate substrate. The method comprises treating the substrate material in a high temperature, high humidity environment for an extended period of time. Dramatic improvements in the useful life of the optical recording medium in which the treated polycarbonate substrate is used have been found to result.

High temperature, high humidity stabilization process for optical

A sulfoalkyl derivative of N-substituted hydroxyethylated polybenzimidazole is disclosed, produced by the reaction of an N-substituted hydroxyethylated polybenzimidazole anion with a sultone. The N-substituted hydroxyethylated polybenzimidazole polymer is first reacted with an alkali hydride to produce the anion of N-substituted hydroxyethylated polybenzimidazole. The N-substituted hydroxyethylated polybenzimidazole anion is then reacted with the sultone to produce a sulfoalkyl derivative of the N-substituted hydroxyethylated polybenzimidazole polymer. These derivatives find great use as ion exchange devices.
