A biorenewable tackifier made from selected terpene monomers. This product can be used to tackify natural rubber, synthetic elastomer, and some polyolefin adhesives. The aliphatic nature of this product allows compatibility with the mid-block of styrene-isoprene-styrene block copolymers while limiting interaction with the styrenic end-blocks providing a balance of tack, peel, cohesive strength, and heat resistance. It has a narrower molecular weight distribution, which improves compatibility with some adhesive elastomers.
