“…The polyalkylvinyl ether phases were prepared by suspension copolymerization of n-octadecylvinyl ether (Lancaster, Mühlheim am Main, Germany) and n-butylvinyl ether with TDVE or DVB as crosslinkers as described elsewhere [12]. This mixture was added to an aqueous solution containing 2% wt polyvinyl alcohol (72,000).…”

“…The phases degrade outside the pH range 2-7, owing to hydrolysis of the siloxane bond at low pH and dissolution of the silica gel at high pH [1]. Despite this, totally organic sorbents are becoming increasingly popular [7][8][9] and because ST-DVB porous copolymers can be easily modified different HPLC packings with polar functional groups are now available. The importance of accurate definition of stationary phase quality was stressed by Karch et al [4] and Jandera et al [5].…”

Dimethyldichlorosilane has been used to deactivate the hydroxyl groups present in the skeleton of the porous polymer formed from the methacrylic ester of p,p'-dihydroxydiphenylmethane diglycidyl ether and divinylbenzene. The influence of chemical modification of the copolymer on its chromatographic behavior has been studied. The retention indices of five homologous series and test compounds were calculated to determine the selectivity of the packings.

Linear and branched alkanes are oligomers of polyethylene. Alkanes with higher molar masses are called waxes. These substances are widely used as fuels, oils, lubricants, etc. and for these reasons many groups have tried to analyse, separate and characterise alkanes by various methods, including liquid chromatography. Alkanes may be separated according to their size in solution by SEC. In addition to chromatographic systems separating in the SEC mode, various sorbent-solvent systems have been published, where alkanes have been separated one from another by adsorption and/or precipitation mechanism. The mobile phase is either a nonpolar solvent or a polar solvent or a mixture of a solvent and a non-solvent for alkanes. Even near critical conditions, which have several advantages for applications of HPLC in polymer analysis, have been identified for alkanes. Moreover, selective separations of branched alkanes according to their structure have been published. In the majority of these published studies, solvents with low boiling points have been used as the mobile phases, which do not allow dissolution of crystalline polyolefins at atmospheric pressure. However, taking into account experiences with the separation of alkanes, new HPLC systems for the separation of polyolefins may be developed. This is a major challenge and first results are presented in this contribution.
