将铑（I）络合物键合在苯乙烯（ST）、二乙烯基苯（DVB）和二苯基对苯乙烯基膦（DPSP）三元共聚物上。在气相中，在40 - 90 °C下，在该聚合物结合的金属络合物上研究了乙烯的氢化。由于指前因子的可逆不连续变化，催化活性在约68 °C突然变化，这归因于聚合物的玻璃化转变。
Rhodium(I)-complex was bound on a ternary copolymer of styrene (ST), divinyl benzene (DVB) and diphenyl-p-styrylphosphine (DPSP). The hydrogenation of ethylene was studied over this polymer-bound metal complex, at 40∼90 °C in gas phase. The catalytic activity changed abruptly at around 68 °C due to the reversible discontineous change In the pre-exponential factor, which was ascribed to the glass transition of the polymer.
