US 10,851,270 B2 · Adhesives comprising polyindane resins

Abstract

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.
