Abstract:
Foam compositions comprise at least an ethylene/α-olefin interpolymer. The ethylene/α-olefin interpolymers of the present disclosure are multi-block copolymers comprising at least one soft block and at least one hard block. The foam compositions can further comprise a blowing agent and a cross-linking agent. Methods of making the foam compositions and foamed articles made from the foam compositions are also described.
Abstract:
Disclosed herein is a foam composition comprising an olefin copolymer that comprises ethylene and an α-olefin or propylene and an α-olefin; an ionomer that comprises copolymer of ethylene and a carboxylic acid; where the ionomer is neutralized with a metal ion; a crosslinking agent; and a blowing agent. Disclosed herein is a method of manufacturing a foam composition comprising blending together an olefin copolymer that comprises ethylene and an α-olefin or propylene and an α-olefin; an ionomer that comprises copolymer of ethylene and a carboxylic acid; where the ionomer is neutralized with a metal ion; a crosslinking agent; and a blowing agent to form the foam composition; heating the composition to activate the blowing agent; and crosslinking the composition.
Abstract:
A film having first and second segments arranged along the film's width direction. The second segments are more elastic than the first segments. The first segments can include a polymer and a diluent that is miscible with the polymer at a temperature above a melting temperature of the polymer but that phase separates from the polymer at a temperature below a crystallization temperature of the polymer, or the first segments can include at least one of a beta-nucleating agent or thermally induced phase separation caused by a diluent. Laminates and absorbent articles including such films are also disclosed. A method of making the film is also described.
Abstract:
A film having first and second segments alternating across the film's width direction. The second segments are more elastic than the first segments. The first segments absorb light at a selected wavelength to a greater extent than the second segments. At least some of the first segments have apertures through their thicknesses, and a percentage of area of the first segments occupied by the apertures is greater than a percentage of area occupied by any apertures that may extend through the second segments. Laminates and absorbent articles including such films are also disclosed. A method of making the film is also described. The method includes forming apertures in at least some of the first segments using a laser at the selected wavelength. The first segments have a sufficient absorbance of light at the selected wavelength to form apertures through their thicknesses.
Abstract:
A film having first and second segments alternating across the film's width direction. The second segments are more elastic than the first segments, and a force required to stretch the second segments is less than a force required to stretch the first segments. At least some of the first segments have apertures through their thicknesses, and a percentage of area of the first segments occupied by the apertures is greater than a percentage of area occupied by any apertures that may extend through the second segments. Laminates and absorbent articles including such films are also disclosed. A method of making the film is also described.
Abstract:
Green technology method is described a combination of prototype processing for the preparation, purification and modification of micro- and nano-size scale clay particles from mineral resources of Turkey using novel functional organic intercalants as reactive nanofillers, alternating copolymers of maleic anhydride and their grafts with biopolymers as reactive compatibilizers and bioactive matrix polymers, thermoplastics, thermosets and rubbers as processible matrix polymers, which are useful for preparation of novel high performance engineering and bioengineering polymer layered silicate nanomaterials (nanofims, nanocoatings, nanofibers, nanomedicals and etc.).
