Davankov-type resins

Davankov-type resins can be defined as the first kind of hypercrosslinked polymers. The single-phase hypercrosslinked polystyrene... 

The book was initially eonstrueted with a historical development sequenee of porous polymers eombined with illustrations of structure-property correlations. Eaeh ehapter provides an example of a particular element of porous polymers. Chapter 1 provides a summary of porous polymers and discusses the relationship between structure and function. In Chapter 2, the design principles of porous polymers are diseussed and modification methods are introdueed, while Chapter 3 introduees the synthetic routes and reactions used in polymerization. An understanding of these reactions is essential if we are to understand the origin of the ordered or amorphous structure of porous polymers. Chapter 4 describes the first porous polymers, developed in the 1990s and named hypercrosslinked polymers or Davankov-type resins. Chapter 5 focuses on the first soluble polymer with intrinsic microporosity that was reported in 2002. Meanwhile, Chapter 6... 

As a result of certain drawbacks attached to coated silica gel CSPs, they could not be used for preparative separations. However, the literature provides some reports on the preparative chiral separations on the bonded CSPs. The bonded CSPs are suitable for use at a preparative scale but the yield is very poor due to poor loading capacities. Davankov et al. [73] packed a column with 300 g of the L-hydroxyproline-type resin and used the chiral separation at a preparative scale.

Cross-linked polystyrene resins incorporating chiral amino acids were utilized as the chiral stationary phases (CSPs) in CLEC [6,21], Davankov et al. [12] reported the use of a resin incorporating L-proline in a polystyrene-type matrix. The resin was prepared by reacting L-proline with the chlormethylated styrene-divinyl-...
