Abstract: A thermoplastic core-sheath fiber comprises: a polymer fiber core having a coextensive sheath layer disposed thereon, and an electrostatic charge enhancing additive. The sheath layer may comprise poly(4-methyl-1-pentene) and the fiber core and the sheath layer have different compositions. At least one of the fiber core or the sheath layer comprises an electret charge. A nonwoven fibrous web comprising the core-sheath fibers and a respirator including the nonwoven fibrous web are also disclosed.

Abstract: Abrasive articles including a nonwoven fibrous substrate having a plurality of fibers, and a multiplicity of shaped abrasive particles, each shaped abrasive particle adhered to a corresponding fiber, each shaped abrasive particle having a length (L) and a width (W) determined in a direction substantially orthogonal to the length, the ratio of the length to the width defining an aspect ratio (L/W) of at least 1.1, each abrasive particle is oriented relative to its corresponding fiber, and more than 50% of the abrasive particles are oriented with respect to their corresponding fiber such that the abrasive particle length extends generally outwardly away from a surface of the corresponding fiber as determined visually using the Orientation Test. The shaped abrasive particles may have the geometric shape of a polygonal prism having two faces and at least three sides thereon. Methods of making the abrasive articles are also disclosed.

Abstract: Benzotriazole phenols with substituents either ortho to the phenol hydroxyl group and/or para to the phenol hydroxyl group can be prepared from the unsubstituted benzotriazole phenol by coupling reactions. The ortho substituent group can be a simple alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenol to another benzotriazole phenol group.
