Carboxy-terminated oligostyrenes, prepared by radical polymerization using a dicarboxy-functional initiator, can efficiently be separated by gradient high performance liquid chromatography (HPLC). On a normal phase chromatographic system, comprising a silica gel stationary phase and a tetrahydrofura

Abstract
Hydrocarbon groupβtype analysis of gasolineβrange materials is a very important method for evaluating feedstocks and products in the petroleum industry. In this paper the method of groupβtype analysis of gasolineβrange materials by high performance liquid chromatography is investigated.
The results demonstrte that the separation of saturates and olefins can be accomplished with reactivated and cooled columns. The lowβtemperature columns and the use of nβhexane as an eluent play a particularly important role in the improvement of the separation.
