Abstract: Disclosed is a UV stabilized polyarylene sulfide composition, methods of forming the composition, and UV stabilized products that can be formed of the composition. The UV stabilized polyarylene sulfide composition can include a reactively functionalized polyarylene sulfide polymer in conjunction with a UV stabilizer. The reactivity of the polyarylene sulfide polymer is formed during melt processing via reaction of a reactively functionalized disulfide compound with a starting polyarylene sulfide. The reactivity of the polyarylene sulfide can encourage interaction between the polyarylene sulfide polymer and the UV stabilizer, which can improve dispersion of the UV stabilizer throughout the composition and improve miscibility between the polyarylene sulfide polymer and the UV stabilizer. Products can incorporate high concentrations of UV stabilizer and/or can be formed to very small cross sectional dimensions without phase separation between the UV stabilizer and the polyarylene sulfide.

Abstract: Improvements in preventing heat- and moisture-shrink problems in specific polypropylene tape fibers are provided. Such fibers are basically manufactured through the initial production of polypropylene films or tubes which are then slit into very thin, though flat (and having very high cross sectional aspect ratios) tape fibers thereafter. Such fibers (and thus the initial films and/or tubes) require the presence of certain compounds that quickly and effectively provide rigidity to the target polypropylene tape fiber after heat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and upon allowing such a melt to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling.

Abstract: A composite prepreg material (10) with improved resistance to core crush and porosity incorporates a plurality of different fiber forms having varying cross-sectional configurations. Preferably, the fibers are interwoven in a warp (14) and fill (18) perpendicular orientation pattern. The varying cross-sectional configurations of the different fiber forms causes the fiber forms to have different levels of spreadability and frictional resistance to movement of the fiber. The present invention overcomes the susceptibility to many defects (specifically core crush and porosity) associated with composite material of a single fiber form having a set cross-sectional configuration, by incorporating multiple fiber forms having varying cross-sectional configurations. This multi-fiber form incorporation allows the strengths of one fiber form's properties to help compensate for the weaknesses of another fiber form's properties, and vice versa.
