| description | Described herein are hydrocarbon polymer modifiers for use in a variety of applications. The hydrocarbon polymer modifier comprises a cyclic component and has a glass transition temperature and Mn defined by the following two relationships: (1) Tg > = 95-2.2 * (% HAr), and (2) Tg > = 125-(0.08 * Mn), and an aromaticity content of less than or equal to 6 mol%, where Tg is the glass transition temperature of the modifier expressed in DEG C,% HAr represents the content of aromatic protons in the hydrocarbon polymer modifier, and (3) Tg > = 125-(0.08 * Mn) represents the content of aromatic protons in the hydrocarbon polymer modifier. And Mn represents the number average molecular weight of the hydrocarbon polymer modifier, and the cyclic component is selected from fractions from a petroleum refinery stream, and/or C4, C5 or C6 cyclic olefins and mixtures thereof, and wherein the hydrocarbon polymer modifier has a number average molecular weight (Mn) of between 150 and 800 g/mol.
