    摘要： Novel elastomeric compositions which contain at least one thermoplastic elastomer and at least one phase change solvent and at least one processing oil. The presence of particular processing oils, e.g., poly(alphaolefins), provide a means to increase mechanical properties compared to commercially available mineral oils. The oils of the present invention are chosen as to minimize the depression of glass transition temperature of the hard-block of the thermoplastic elastomer. The phase change behavior of these materials produce elastomeric compositions that exhibit lowered viscosity and lowered processing temperature without substantially compromising the mechanical properties of the elastomeric composition.

    摘要： Variable stretch composites having one or more first elastomeric members disposed on a first region of an extensible substrate, and one or more second elastomeric members disposed on a second region of the extensible substrate which different from the first elastomeric members to provide variable properties to said regions of the composite. 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 variable 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 variable stretch composites.

    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.
