Abstract: Compositions containing tri-cyclopentadiene and processes for making same. In some embodiments, the composition can include 1 wt % to 6 wt % of TCPD-7; 5 wt % to 25 wt % of TCPD-3; 15 wt % to 30 wt % of TCPD-5; and 55 wt % to 75 wt % of TCPD-1, where all wt % values are based on the combined weight of TCPD-7, TCPD-3, TCPD-5, and TCPD-1 in the composition. In some embodiments, the composition can further include di-cyclopentadiene. In other embodiments, the composition can further include di-cyclopentadiene, tetra-cyclopentadiene, and optionally one or more oligomers heavier than tetra-cyclopentadiene. In some embodiments, the composition can be made via a continuous process.

Abstract: Methods for resin hydrogenation and decoloration may comprise reacting a resin mixture with a sulfided bimetallic catalyst and excess hydrogen under conditions effective to form a hydrogenated resin mixture, the resin mixture comprising an oligomerized reaction product of at least one polymerizable monomer containing an olefinic unsaturation and a solvent; providing the hydrogenated resin mixture directly to a noble metal catalyst; and reacting the hydrogenated resin mixture in the presence of the noble metal catalyst under conditions effective to form a decolorized resin mixture. Decolorized resin compositions comprising a decolorized resin mixture formed in accordance with the foregoing may have a yellowness index of about 10 or below, as measured by ASTM E313.
