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.

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, adhesive formulations are provided that comprise at least one polyindane resin, which may be used to replace or enhance the functionality of existing hydrocarbon resins typically used in adhesive formulations. Compositions comprising at least one thermoplastic elastomer and at least one polyindane resin are also provided.

Adhesives comprising polyindane resins

A low z-average molecular weight, high softening point polystyrene resin having a narrow molecular weight distribution, as well as methods of making and using the same, are provided. The use of an inert solvent and/or the order of addition of reactants during polymerization may contribute to the unique properties of the final homopolymeric resin. The polystyrene resin can be partially or fully hydrogenated and may have particular use as a tackifying agent in a variety of hot melt adhesive and rubber compositions.
