Abstract
A process for hydrogenating polymers which are derived from olefin units containing 4 carbon atoms is disclosed whereby white oils which exhibit a low iodine value (e.g., below 0.26) are obtained under relatively mild reaction conditions. The hydrogenation is effected in the presence of a catalyst comprising platinum on an alumina support exhibiting a total pore volume of at least 0.25 ml/g of which about 90 to 98% are provided by pores the mean size of which is below 100A.
