A series of Ethylene/1-Octene/1,7-Octadiene terpolymers were prepared in a manner similar to the procedure described in Example 20. The polymerization reaction was carried out in 300 ml stainless autoclave equipped with a mechanical stirrer. The same qualities of toluene, MAO, and catalyst were introduced into the reactor as described for Example 20 and various volumes of 1-octene and 1,7-octadiene (11.5 ml/0.5 ml, 11 ml/1 ml, 10 ml/2 ml, 8 ml/4 ml) were injected to form the sample series Example 21 to 24, respectively. The polymerization was quenched with methanol after 3 minutes of reaction at 60° C. under 220 psi pressure of ethylene gas. The gel content of each resulting terpolymer was determined as discussed in Example 20. Only the fully cross-linked polymers were subjected to oil absorption with a small piece of sample (about 0.5 g) at room temperature. In addition, the absorption study was also extended into the individual crude oil components, including alkanes (such as heptane), cycloalkanes (such as cyclohexane) and aromatic hydrocarbons (toluene and benzene). The absorption capacity data for the various crosslinked samples of Examples 21-24, respectively, in various hydrocarbons are summarized in Table 5.
