Functional monomers selection

Figure 9 Functional monomers selected for the screening of Example 3 (imprinting of phenytoin). Figure 9 Functional monomers selected for the screening of Example 3 (imprinting of phenytoin).
Considering functional group complementarity, other commodity monomers may also be used. Thus for templates containing acid groups, basic functional monomers are preferably chosen. The 2- or 4-vinylpyridines (VPY) are particularly well-suited for the imprinting of carboxylic acid templates and provide selectivities of the same... [Pg.171]

It is possible to exercise control over this form of compositional heterogeneity (i. e. the functionality distribution) by careful selection of the functional monomer and/or the transfer agent taking into account the reactivities of the radical species, monomers, and transfer agents, and their functionality.11 250 Relative reactivities of initiator and transfer agent-derived radicals towards monomers are summarized in Section 3.4. Some values for transfer constants are provided in Chapter 6. [Pg.384]

Again, the imprinted films show high selectivity towards parathion in comparison to similar organophosphates. The binding has been shown to be very sensitive to the type of functional monomer used for imprinting, and that rational design of the matrix components is an... [Pg.154]

This general method either involves low-molar-mass azo compounds having additional functionality, which can be used to start a polymerization of a vinyl monomer selectively, or a ring-opening addition but also to participate in cocondensation reactions. [Pg.184]
