By a method similar to isoporous polystyrene synthesis, poly(4-vinylpyridine) has been cross-linked with dibromoalkanes to give insoluble networks containing pyri-dinium ions (26)113). 

S)-amino acicis, mexiule C, two stereoisomers, and tethered to polystyrene via mcxlule B, two stereoisomers) was prepared by encoded split synthesis on 100 pm polystyrene synthesis beads so that different library members were segregated on different beads (i.e. one bead, one chiral SO). This library was then screened by a two-colour differential binding method amino acid SAs were labelled via a linker with red ((/ )-amino acids) and blue ((S)-amino acids) dyes and the chiral beads treated with an equimolar mixture of the labelled SA enantiomers. Enantioselective binding beads are either red or blue, whereas unselective beads are brown.

Tubular and columnar apparatus (apparatus length-to-diameter ratio L/d > 100) including screw equipment relate to plug-flow reactors type [7,8]. Plug-flow reactors are applied for many of gas-phase reactions realized in production quantities, in particular for ethylene polymerization under high pressure conditions [9], and for some liquid-phase reactions, for example polystyrene synthesis in columns and other rubbers and plastics productions. Near 10% of polymer and 30% of fibers manufacture are produced in apparatus of such types [10].

This type of SEC-MS hyphenation has been applied to a wide variety of homopolymers and copolymers amongst them are polyacrylates, polyesters, polyethers, polyamides, resins, polycarbonates, proteins, and polystyrene. Synthesis optimization, investigation of the degradation behavior of polymers, polymer aging, and deformulation have been the goals of the analysis.
