Molecularly imprinted polymers were prepared and tested in different way. 1-methyl-2-piperidinoethylester of 4-decyloxyphenylcarbamic acid was used as template for imprints formation. Acrylamide, 4-vinylpyridine and methacrylic acid as monomers and methanol and acetonitrile as a porogene were used. Non-imprinted polymers (NIP) were prepared for each imprinted polymer by the same procedure. Polymers were employed as sorbents for solid-phase extraction (SPE). In this work the influence of polymerization mixture composition on polymer properties, such as capacity and selectivity, was investigated. The influence of alkoxy-chain length and position on benzene ring on the selectivity of polymers was also investigated.
