Abstract
Abstract This invention is directed to a polymeric composition: (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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
113 words
A fluorescent polymeric 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 of carboxylic acid, 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
113 words
A fluorescent polymeric 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 of carboxylic acid, 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
54 words

Claim 4
Dependent Claim
30 words
A composition according to 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
44 words
A composition according to claim 3, said composition comprising: (g) 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.
