A hydrocarbon resin having a Ring and Ball (R&B) softening point of 70-150[deg]C, a max. Mz of 4000, a max. Mw of 2500 and a max. polydispersity (Pd) of 3.0, comprises a thermally polymerised copolymer made from: (I) 40-90 wt.% (based on total monomers) cyclic diolefin component comprising at least 50 wt.% dicyclopentadiene (DCPD); and (II) 10-60 wt.% vinyl aromatic component(s) of formula (I), where R1 = H or 1-10C alkyl at the m- or p-position; and R2 = 1-10C alkyl or 2-methyl-2-phenylpropyl.
