Tires comprising polyindane resins and uses thereof
The present invention is generally related to various types of compositions that comprise a polyindane resin. In particular, the polyindane resins may be utilized in various polymer-based and elastomer-based formulations in order to enhance several properties and characteristics of those formulations. More specifically, elastomeric compositions are provided that comprise at least one polyindane resin, which may be used to replace or enhance the functionality of existing hydrocarbon resins used in elastomeric formulations. The elastomeric compositions may be used to produce various tire components.
1. A tire component comprising an elastomeric composition, said elastomeric composition comprising at least one elastomer and at least one polyindane resin; wherein said elastomer is selected from the group consisting of natural rubber, styrene-butadiene rubber, butadiene rubber, ethylene propylene diene polymers, ethylene-propylene copolymers, butyl rubber, and halobutyl rubbers; wherein said polyindane resin exhibits a glass transition temperature (“Tg”) in the range of 10° C. to 150° C.; wherein said polyindane resin comprises a number average molecular weight (Mn) in the range of 300 g/mol to 5,000 g/mol, and wherein there is a substantial absence of polyphenylene ether.
2. The tire component of claim 1 , wherein said elastomeric composition comprises 1 to 100 phr of said polyindane resin.
3. The tire component of claim 1 , wherein said elastomeric composition comprises 3 to 60 phr of said polyindane resin.
4. The tire component of claim 1 , wherein said polyindane resin is derived from a diisopropenyl-substituted aromatic compound.
5. The tire component of claim 1 , wherein said tire component comprises a tire tread, tire subtread, tire undertread, and/or tire sidewall.
6. A tire component comprising an elastomeric composition, said elastomeric composition comprising at least one elastomer, a polyindane resin, and one or more fillers; wherein said elastomer is selected from the group consisting of natural rubber, styrene-butadiene rubber, butadiene rubber, ethylene propylene diene polymers, ethylene-propylene copolymers, butyl rubber, and halobutyl rubbers; wherein said polyindane resin exhibits a glass transition temperature (“Tg”) in the range of 10° C. to 150° C.; wherein said polyindane resin comprises a number average molecular weight (Mn) in the range of 300 g/mol to 5,000 g/mol, and wherein there is a substantial absence of polyphenylene ether.
7. The tire component of claim 6 , wherein said elastomeric compositions comprises 1 to 100 phr of said polyindane resin.
8. The tire component of claim 6 , wherein said elastomeric composition comprises 3 to 60 phr of said polyindane resin.
9. The tire component of claim 6 , wherein said polyindane resin is derived from a diisopropenyl-substituted aromatic compound.
10. The tire component of claim 6 , wherein said fillers comprise silica, carbon black, or a combination thereof.
11. The tire component of claim 6 , wherein said tire component comprises a tire tread, tire subtread, tire undertread, and/or tire sidewall.
