Polymer porosity and swelling

Depending on whether a solvent or a non-solvent is used as diluent, large differences in swelling between the materials may be seen [13,40]. In the molecular imprinting of L-PA (model system), a number of MIPs were prepared using a standard recipe with 83% cross-linker but with different diluents (see also Chapter 5) [13]. To what extent do the solubility parameters then correlate with the polymer morphology or, in other words, which solvents are good and which are bad in the polymerisation of EDMA and MAA. As described in Chapter 5, maximum 

SOLUBILITY PARAMETERS, HYDROGEN BOND CAPACITY AND REFRACTIVE INDICES OF SOLVENTS USED FOR PREPARING MIPs 

The solubility parameter d has been divided into one dispersive term d, one polar term bp and one hydrogen bonding term (5h. H-bond is a measure of the hydrogen bonding capacity of the solvent in terms of both donor and acceptor ability P = poor, M = moderate and S = strong. D = refractive index.
