| Hydrocarbons are divided into groups of which those of especial interest to geologists are the paraffin, cycloparaffin and aromatic groups. |
| The processability of decalin, a two-fused ring cycloparaffin, in the absence and presence of USY catalysts of different zeolite crystallite sizes is investigated under actual FCC conditions. |
| In a preferred embodiment of the process of the present invention, the cycloparaffin is cyclohexane or cyclododecane. |
| The copolymer chains containing 1,2-disubstituted cycloparaffin structures form more kinks and take shorter time to totally collapse into a single globule than the others. |
