Provided are: a highly durable polymer having a high hole-injection/transport capacity; and a composition for an organic electroluminescent element, which contains the polymer. The polymer contains a repeating unit represented by the following Formula (1) or a repeating unit represented by the following Formula (2) (wherein, Arand Areach represent an aromatic hydrocarbon group optionally having a substituent, or an aromatic heterocyclic group optionally having a substituent; X represents —C(R)(R)—, —N(R)—, or —C(R)(R)—C(R)(R)—; Rand Ras well as Rand Reach independently represent an alkyl group optionally having a substituent; Rand Reach independently represent an alkyl group optionally having a substituent, an alkoxy group optionally having a substituent, or an aralkyl group optionally having a substituent; and Rto Rand Rto Reach independently represent hydrogen, an alkyl group optionally having a substituent, an aralkyl group optionally having a substituent, or an aromatic hydrocarbon group optionally having a substituent).

A high-octane gasoline is produced by the conversion of a light hydrocarbon containing C.sub.2 -C.sub.7 paraffins and/or C.sub.2 -C.sub.7 olefins using a crystalline aluminogallosilicate containing about 0.1-2.5% by weight of aluminum and about 0.1-5% by weight of gallium in the skeleton thereof and having a particle size in the range of about 0.05-20 .mu.m, with at least 80% by weight of the crystalline aluminogallosilicate having a particle size of 0.1-10 .mu.m.
