The present invention provides a copolymer of 1,3,7-octatriene and isoprene having a narrow molecular weight distribution (Mw/Mn) and a hydride thereof. Furthermore, in a production method of a copolymer containing a structural unit derived from 1,3,7-octatriene and a structural unit derived from isoprene, high raw material conversions are achieved for a short polymerization time. Specifically, the copolymer is a copolymer containing a structural unit derived from 1,3,7-octatriene and a structural unit derived from isoprene and is a copolymer having a molecular weight distribution (Mw/Mn) of less than 1.44, or the like.

A copolymer of ethylene and of a 1,3-diene of formula CH.sub.2CRCHCH.sub.2 is provided. The ethylene units represent between 50 mol % and 95 mol % of the ethylene units and of the units of the 1,3-diene, and the units of the 1,3-diene of 1,2 and 3,4 configuration represent more than 50 mol % of the units of the 1,3-diene. The symbol R represents a hydrocarbon chain having from 3 to 20 carbon atoms. Such a copolymer exhibits an improved compromise between the degree of crystallinity and the stiffness and makes it possible to widen the field of application of ethylene-rich diene copolymers in rubber compositions.

An adhesive composition made from an elastomer and a tackifying resin. The tackifying resin includes a farnesene polymer or copolymer having the following properties: i) less than 10 weight percent of volatile organic compounds; ii) Mn between 300 Da and 1000 Da; iii) Mw between 400 Da and 3000 Da; iv) Mw/Mn between 1.00 and 3.00; v) Tg between 50 C. and 20 C.; and vi) viscosity between 400,000 cP and 1,000,000 cP at 25 C. A method of making the farnesene-based polymer or copolymer includes combining a farnesene monomer and a solvent and optionally adding one or more co-monomers selected from dienes, branched mono-olefins, and vinyl aromatics, to provide a monomer feed, and polymerizing the monomer feed by combining it with a Friedel-Crafts initiator in a vessel. The farnesene-based polymer or copolymer tackifier may be combined with one or more elastomers and one or more other tackifiers to form an adhesive composition.
