    摘要： Phase change solvents for thermoplastic polymers to provide blended compositions. Above the phase change temperature of the solvent, the phase change solvent solubilizes or intimately mixes with the thermoplastic polymer. Below the phase change temperature of the solvent, the phase change solvent solidifies or crystallizes within the thermoplastic matrix. The phase change behavior of these materials produce blended compositions that exhibit lowered shear viscosity and lowered processing temperature without substantially compromising mechanical properties of the thermoplastic polymer, such as hardness. The present invention also relates to a method of improving the processability of a thermoplastic polymer using the phase change solvent.

    摘要： A stretch composite having one or more elastomeric members disposed on at least one region of an extensible fibrous substrate to provide stretch properties to a targeted region of the substrate. The composite has been incrementally stretched to at least partially break up the structure of the substrate in order to reduce its resistance to stretch. The stretch composites are useful for disposable and durable articles, such as disposable absorbent articles including diapers, pull-on diapers, training pants, incontinence briefs, catamenial garments, baby bibs, and the like, and durable articles like garments including sportswear, outerwear and the like. The present invention also relates to methods of forming such stretch composites.
