Abstract: Pressure sensitive adhesives comprising a linear block copolymer having a rubbery block and at least one glassy block; a multi-arm block copolymer having at least three arms, each having both a rubbery block and a glassy block; a first high glass transition temperature tackifier compatible with the rubbery blocks; a second high glass transition temperature tackifier having compatible with the glassy blocks; and at least one of a low Tg tackifier, a plasticizer, and combinations thereof, are disclosed. Tapes that include such adhesive, methods of making such tapes, and bonded composites using such adhesives and tapes are also disclosed.

Abstract: Adhesive compositions comprising a high molecular weight acrylic copolymer and a low molecular weight copolymer are disclosed. Adhesive articles and methods of making adhesive compositions and articles are also described.

Abstract: Disposable absorbent articles comprising an absorbent material and a degradable thermoplastic polymer composition comprising an aliphatic polyester and an antimicrobial composition. The antimicrobial composition includes an antimicrobial component and an enhancer component. The aliphatic polyester and antimicrobial composition are formed into webs by melt extrusion, such as nonwovens and films, that are incorporated into disposable absorbent articles, such as disposable infant diapers, adult incontinence articles, feminine hygiene articles such as sanitary napkins, panty liners and tampons, personal care wipes and household wipes to provide odor control, control of microbial growth, and control of microbial toxin production.

Abstract: Antimicrobial compositions comprising aliphatic polyester, and an antimicrobial component effective for antimicrobial activity, and, in some embodiments, an enhancer. Example: blend of poly(lactic acid) polymer (55g) with propyleneglycol monolaurate antimicrobial component (9g), and benzoic acid enhancer (1g). Inventive resin compositions are effective against gram negative and gram positive bacteria, mold and mildew. Preferred compositions comprise materials that are GRAS (Generally Regarded As Safe).

Abstract: The present disclosure provides an apparatus and methods for producing co-extruded composite webs including a continuous layer of an extruded matrix material, and a multiplicity of included phases embedded in the continuous layer. The included phases are surrounded by the matrix material to form a single-layer composite web within a feed block having an internal die body. The included phases are separate from each other by being discontinuous in the cross-web direction, but the included phases may be substantially continuous in the down-web direction. In some exemplary embodiments, the co-extruded single-layer composite web may be used in a single-layer or multi-layer article. In other exemplary embodiments, the single-layer co-extruded composite web may be in the form of a sheet, a film, a blown film, a filament, a fiber, a tube, and the like.
