Abstract
Abstract This invention relates to phosphoresent, polymer-containing compositions suitable for use in footwear and to phosphorescent shoes, shoe soles, and other molded or extruded shoe parts made from such compositions. One aspect of this invention is directed to a polymeric composition comprising: (a) between about 25 and 75% by weight of an elastomeric polymer; (b) between about 20 and 50% by weight of a processing oil; (c) between about 0.005 and 0.5% by weight of at least one stabilizer; and (d) between about 3 and 30% by weight of a phosphorescent pigment. This invention relates to phosphoresent, polymer-containing compositions suitable for use in footwear and to phosphorescent shoes, shoe soles, and other molded or extruded shoe parts made from such compositions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
A phosphorescent shoe sole made in whole or in part from a composition comprising (a) about 25-75% by weight of an elastomeric polymer selected from the group consisting of styrenic block copolymers suitable for making footwear, footwear soles, and other footwear parts; (b) about 20-50% by weight of a processing oil selected from the group consisting of napthenic hydrocarbon oils suitable for use as polymer plasticizers and extenders and mixtures thereof; (c) about 0.005-1% by weight of a stabilizer selected from the group consisting of hydroxybenzoate ester ultraviolet stabilizers, hindered phenolic anti-oxidant compounds, thioesters or carboxylic acids, and mixtures thereof; and (d) about 3-30% by weight of a phosphorescent compound, capable of imparting phosphorescent properties to said composition and articles made therefrom.
Claim 2
Dependent Claim
122 words
A phosphorescent shoe sole made in whole or in part from a composition comprising (a) about 25-75% by weight of an elastomeric polymer selected from the group consisting of styrenic block copolymers suitable for making footwear, footwear soles, and other footwear parts; (b) about 20-50% by weight of a processing oil selected from the group consisting of napthenic hydrocarbon oils suitable for use as polymer plasticizers and extenders and mixtures thereof; (c) about 0.005-1% by weight of a stabilizer selected from the group consisting of hydroxybenzoate ester ultraviolet stabilizers, hindered phenolic anti-oxidant compounds, thioesters or carboxylic acids, and mixtures thereof; and (d) about 3-30% by weight of a phosphorescent compound, capable of imparting phosphorescent properties to said composition and articles made therefrom.
Claim 3
Dependent Claim
56 words
The shoe sole of claim 1, said composition further comprising (e) about 0-25% of a modifying polymer selected from the group consisting of high density polyethylene, ethylene vinyl acetate, poly-(alpha-methylstyrene) resin, polybutadiene resin, high styrene resin, crystal polystyrene, high impact styrene resin polymers and copolymers, and mixtures thereof; and (f) about 0-20% precipitated, finely divided silica.
Claim 4
Dependent Claim
30 words
The shoe sole of claim 2, said composition further comprising a filler selected from the group consisting of nepheline syenite, cellulosic fibers, polyester fibers, acrylic fibers, sawdust, and ground cork.
Claim 5
Dependent Claim
43 words
The shoe sole of claim 3, said composition comprising about 25-35% of said elastomeric polymer, about 20-30% of said processing oil, about 0.005-1% of said stabilizer, about 3-10% of said phosphorescent compound, about 5-15% of said modifier and about 5-15% of said silica.
Claim 6
Dependent Claim
45 words
The shoe sole of claim 4, wherein said elastomeric polymer is an oil-extended polystyrene polybutadiene block copolymer, said modifying polymer is poly-(alpha-methylstyrene) resin and crystal polystyrene, said stabilizer comprises 2,4-di-tertiary butylphenyl-3,5-di-tertiary butyl-4-hydroxybenzoate, a hindered phenylic anti-oxidant and dilaurylthiodipropionate, and said flow modifier is precipitated silica.
Claim 7
Dependent Claim
25 words
The shoe sole according to claim 5, wherein said composition contains about 0.005-0.06% of said hydroxybenzoate, 0.005.0.5% of said anti-oxidant and 0.005-0.5% of said dilaurylthiodipropionate.
Claim 8
Dependent Claim
21 words
A phosphorescent shoe sole according to claim 1, 2, 3, 4, 5 or 6, said sole being made by injection molding.
Claim 9
Dependent Claim
44 words
A phosphorescent shoe sole according to claim 7 said injection molding comprising melting said composition by heating it to between about 250°-350° F., injecting said heated composition into a mold, filling said mold, waiting for the injected composition to solidify and opening said mold.
