Abstract
Abstract This invention relates to phosphorescent, polymer-containing compositions for use in Glow In The Dark 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 between about 40-50% by weight rubber; 5-10% by weight processing oil; 0-5% by weight stabilizer; and 3-8% by weight phosphorescent material. A sole made according to the present invention for a children's athletic shoe comprises a mass of sole-forming phosphorescent material having peripheral edges and a cushioning element. The `Glow In The Dark` portion of the shoe being visible on both the peripheral edges and underneath surface.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
114 words
A phosphorescent shoe sole made in whole or in part from a composition comprising: (a) about 40-50% by weight of a polybutadiene rubber selected from the group consisting of polystyrene butadiene block copolymers suitable for making footwear; (b) about 5-10% 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 0-5% by weight of a stabilizer selected from the group consisting of ultraviolet stabilizers, antioxidant compounds, thioesters of carboxylic acids, and mixtures thereof; and (d) about 3-8% by weight of a phosphorescent compound, wherein said phosphorescent compound gives said composition, and products made therefrom, phosphorescent properties.
Claim 2
Dependent Claim
114 words
A phosphorescent shoe sole made in whole or in part from a composition comprising: (a) about 40-50% by weight of a polybutadiene rubber selected from the group consisting of polystyrene butadiene block copolymers suitable for making footwear; (b) about 5-10% 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 0-5% by weight of a stabilizer selected from the group consisting of ultraviolet stabilizers, antioxidant compounds, thioesters of carboxylic acids, and mixtures thereof; and (d) about 3-8% by weight of a phosphorescent compound, wherein said phosphorescent compound gives said composition, and products made therefrom, phosphorescent properties.
