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 are provided for passivating and/or solubilizing crosslinked popcorn polymer formed from vinyl aromatic precursors. The passivation and/or solubilization can be performed by exposing the crosslinked popcorn polymer to an aromatics-containing solvent at a suitable temperature and/or by heat treating the crosslinked popcorn polymer in the presence of steam and oxygen followed by exposure to an aromatics-containing solvent. The vinyl aromatic polymer can be exposed to the aromatics-containing solvent for a suitable period of time at a temperature of 200° C. or more. Optionally, the aromatics-containing solvent can be at least partially in the liquid phase during the exposure of the vinyl aromatic polymer.
