Adhesion promoter systems and methods of producing same, the systems including the admixing product of at least 60 percent by weight of a first functionalized polyolefin, and less than 40 percent by weight of a second functionalized polyolefin, based on the total weight of the solid content, and one or more solvents. The second functionalized polyolefin includes homopolymers of propylene or copolymers of propylene with hexene, octene and/or other alpha-olefins. The homopolymers or copolymers have a single unsaturation a terminal succinic anhydride moiety, and additional succinic anhydride substitutions on the polypropylene backbone. The succinic anhydride substitution ranges from about 5 to about 45 weight percent of second functionalized polyolefin.

Adhesion promoter system, and method of producing the same

A reversible, heat-set covered fiber is described, the covered fiber comprising: A. A core comprising an elastic fiber comprising a substantially crosslinked, temperature-stable, olefin polymer, and B. A cover comprising an inelastic fiber. The fiber is heat-set by a method comprising: (a) Stretching the covered fiber by applying a stretching force to the covered fiber; (b) Heating the stretched covered fiber of (a) to a temperature in excess of the crystalline melting point of the olefin polymer for a period of time sufficient to at least partially melt the olefin polymer; (c) Cooling the stretched and heated covered fiber of (b) to a temperature below the crystalline melting point of the olefin polymer for a period of time sufficient to solidify the polymer; and (d) Removing the stretching force from the covered fiber.

Reversible, heat-set, elastic fibers, and method of making and article made from same

Durable stretch fabrics are made and processed from one or more crosslinked, heat-resistant olefin elastic fibers, e.g., a substantially linear, homogeneously branched ethylene polymer. The fabrics can be made by any process, e.g., weaving, knitting, etc., and from any combination of crosslinked, heat-resistant olefin elastic and inelastic ('hard') fibers, e.g., cotton and wool. These fabrics exhibit excellent chemical, e.g., chlorine, resistance and durability, e.g., they retain their shape and feel ('hand') over repeated exposure to processing conditions, e.g., stone-washing, dye-stripping, PET-dyeing and the like, and service conditions, e.g., washing, drying, etc.

Stretch fabrics with improved chemical resistance

The elastic fabric comprising a cross-linked polyolefin fiber, wherein the fabric has retractions both in warp-wise and weft-wise directions of the fabric of 8% or less after treated by dry heat at 65&#xb0; C. for 30 minutes is disclosed. Also disclosed is a process for producing an elastic fabric, comprising: retracting a fabric comprising a cross-linked polyolefin fiber while dyeing the fabric, and then stretching or relaxing the fabric at a stretch ratio of 15% or less to finish the fabric with heat-setting. The present invention relates to an elastic fabric having an excellent chemical resistance and an excellent dimensional stability in the form of a product, which is suitably used for sporting fabrics such as swimming suits, leotards and the like, inner fabrics for ladies as well as outer fabrics, for example.

Elastic fabric and process for producing the same

A foamable polymer composition is described which comprises: a1) a substantially random interpolymer produced from: i) one or more &agr;-olefin monomers; and ii) one or more vinyl or vinylidene aromatic monomers and/or one or more sterically hindered aliphatic or cycloaliphiatic vinyl or vinylidene monomers; and optionally iii) other polymerizable ethylenically unsaturated monomer(s); or a2) an interpolymer comprising polymerized units of ethylene and vinyl acetate; or a3) a combination of the polymers a1) and a2); and b) a polydiorganosiloxane having a viscosity of at least one million centistoke at 25&deg; C.; and c) a foaming agent. The polydiorganosiloxane is useful for improving the abrasion resistance of foams comprising the substantially random interpolymer a1) and/or the ethylene/vinyl acetate interpolymer a2).

Foam compositions from blend of alkenyl aromatic polymers and alpha-olefin/vinyl or vinylidene aromatic interpolymers

Elastic fibers are described that comprise (i) a polyolefin polymer, e.g., a homogeneously branched, preferably substantially linear, ethylene polymer, and (ii) a photoinitiator, e.g., an aromatic ketone, in an amount sufficient to effect at least a partial cross-linking of the polymer when the fiber is exposed to sufficient UV-radiation to activate the photoinitiator. Articles, e.g., fabrics, comprising fibers of this invention, either alone or in combination with one or more other fibers, e.g., cellulose, nylon, etc., exhibit good heat resistance and elasticity at elevated temperatures.

Block copolymer compositions containing substantially inert thermoelastic extenders

A thermoplastic elastomeric blend composition comprising: A) from 99 to 1 weight percent of an elastomer block copolymer comprising at least one segment of a styrenic polymer and at least one segment of an elastomeric saturated olefin polymer; and B) from 1 to 99 weight percent of a linear or substantially linear ethylene/&agr;-olefin interpolymer, and fabricated articles made from such composition.
